Alright, if we're going to play Build Your Wii Successor, here's mine.
Controller: Nintendo 6 (6th console... look, it won't be called Wii 2 or Wii HD... f-ing Pachter) has to be able to do everything the Wii and Gamecube did AND something new and exciting. I firmly believe that N6 must have only ONE main controller. No add-ons (i.e. Motion Plus), no classic controller. The controller has to be able to do everything (motion controls, traditional controls, and whatever new-fangled thingamajig Nintendo has planned) with the same basic controller: remote and nunchuck-esque secondary controller. This simplifies things considerably for consumers and 3rd parties. This, however, means more buttons. For non-gamers, seeing someone playing the game rather than seeing the controller is what made it appealing. Most people didn't see the actual controller at first, they saw someone holding a white stick not playing games the way they're stereotypically played. Adding more buttons won't change that. After all, the DS has an SNES layout and that didn't scare non-gamers away. The 3DS has an analog stick. Nintendo is technically further complicating their handheld and yet it's still going to appeal to the same audience because the microphone and touchscreen negate the presence of more complicated controls. The buttons are there, but do nothing and thus are inconsequential to non-gamer software. This ultimately creates a balance for casual gaming and hardcore gaming. The same principle can be applied to N6. You can make all the buttons do nothing or have them all do the same thing (i.e. "Press any button to continue"), but you can't add more buttons after the fact. Give developers the tools and let them decide how to use them. With DS, Nintendo was all about giving developers more options. With Wii, they were essentially taking options away or making the alternative less appealing (since fewer people, by virtue, would have a classic controller) and essentially forcing developers to make due with the limitations of the Wii remote. Not the best way to win support.
My scanner isn't working so I can't show you any fancy drawings. I'll try my best to describe my set-up.
"Nunchuck": Wireless, no pointer, 3-axis accelerometer, gyroscope, rumble, rechargeable
- Analog stick in main position, D-pad underneath, L and ZL (ZL has digital click) in the back
Remote: Wireless, pointer, Infrared pointer, 3-axis accelerometer, gyroscope, rumble, rechargeable
- traditional A,B,X,Y at the top, Analog Slider (3DS) underneath, minus, home, plus under that, then the speaker and finally 1,2,3,4 at the bottom. R and ZR (ZR has digital click) in the back.
It's basically the Classic Controller separated and shaped like a Remote and nunchuck.
Hardware: Nintendo must make the console as powerful as possible while still promoting efficiency and simplicity and either break even or make the smallest profit possible on hardware (do not sell at a loss). I suggest an MSRP of no more than $300, maybe $350. That means, make the most powerful console they can within the confines of a sub $350 MSRP. I'm not a spec whore. I say this only because it matters to 3rd parties and Nintendo should be trying to support them in any way they can. They're making the games and they can make Nintendo loads more money. Ultimately, what it comes down to: We get quality titles, Nintendo makes money, 3rd parties make money. Everyone wins. Nintendo will likely launch at least a year before Sony and Microsoft and Microsoft showed that with a little forward thinking, you can launch hardware first and still have hardware on the same level as a competitor. If Nintendo can get steady support and become the lead platform, it won't even matter if Sony and Microsoft launch slightly more powerful machines because 3rd parties will develop for N6 and port over. Exclusives are a dying breed, the vast majority of 3rd party titles will undoubtedly be multiplatform as we're already seeing today. Most 3rd party games are developed for 360 and ported to PS3.
Abandon Disc Based Media: No, I'm serious. I detest load times. Nintendo is never going to support DVD/Blu-Ray movie playback and they don't have to. However, if they aren't going to, that's one less reason to continue supporting discs. Therefore, abandoning disc based media in favor of cards is an excellent idea and one that provides numerous benefits including durability and quicker data access. Card based storage is more expensive than discs but the discrepancies between cart/card and disc are far narrower than they were back in the N64/PS1 days. Most modern games do not exceed a double sided DVD. For comparison's sake, you can get 8GB SD card (not saying they should use SD cards for storage, I mean something proprietary like DS) for $15 on Amazon. In a year, it'll be even less and on top of that, 3rd parties buy in bulk so it wouldn't even be that much. Games less than 4GB or 2GB (don't balk, Metroid Prime is less than 2GB and that game is massive) would require even cheaper cards.
Unfortunately, this would mean abandoning non-VC backwards compatibility. I know people love their BC, but Nintendo needs to think about N6 first and foremost, not Wii/Gamecube. While BC is a nice selling point for the first year, maybe 2, ultimately it becomes an afterthought and practically vestigial to most users. Eventually, every successful piece of hardware relies on its own merits. Backwards compatibility is a short-term solution to short handed launches whereas employing a card based storage medium provides major advantages throughout the entire lifespan of the console. While I'd love backwards compatibility, I'd sacrifice it for a more durable console with no load times. This is something gamers will notice immediately as they'll experience it within every single game.
Support SSD, continue to support SD cards: For the same reasons as employing cards. It's faster and more durable. The new Macbook Air models can start up in less than 15 seconds and that's loading OSX. N6 is merely a game console. Imagine getting to the menu screen in 10 seconds. Nintendo NEEDS some sort of massive storage device so it can do everything the competition does: patches (ugh), DLC (facepalm), demos, Virtual Console etc. 3rd parties will appreciate this and so will gamers. While SSD are expensive, the price is likely to continue to drop. Apple integrated flash based storage directly onto the motherboard of the new Macbook Air making flash based storage more common. Additionally, Toshiba, who supplies Apple with those pieces, started selling them as stand-alone SSD today. That said, the prices will likely fall to far more affordable prices by the time N6 launches. I think 128 GB should be more than enough for most people and there's always expansion by (slower) SD cards should space become an issue. Keep in mind, with card based media, installing games to improve load times is no longer necessary.
Virtual Console must support Gamecube and Wii games: Pretty self-explanatory. Most GCN games didn't exceed 1 disc whereas few Wii games filled an entire dual-layed DVD. With compression, the file sizes are likely to be even smaller. This is the best case scenario should Nintendo abandon BC.
Include Wii Sports and Wii Sports Resort on the SSD: It's a nice little bonus incentive that costs Nintendo nothing. I think Nintendo should consider a pack-in game that demonstrates whatever new innovative feature they have planned, but since we have no idea what that might be, I can't really comment on it. Basically, it's the gateway drug... game.
Online, Universal Gamer ID, Integrate 3DS: I bundled these together for a reason. N6 and 3DS should be companion hardware capable to sharing information (Mii, Nintendo points etc.). Of course, a universal ID would help out tremendously. 3DS is likely to sell well; many people will have one. It could be used as an alternative controller option for some games, but rarely a requirement as few games could get away with that. It could potentially share GCN and under VC games too.
Not much more needs to be said of Nintendo's online structure. It needs to offer a similar experience to Xbox Live. It may not need all the bells and whistles, but a strong, consistent connection without lag, voice chat, friends list are all must-haves.
