For those who think that the Wii 2 will come out in 2011, what makes you think that? It is still easily beating both the Xbox 360 and PlayStation 3 and is still $200. When sales start to slow down, they just drop the price and boost them back up. Nintendo is also actually making money on the Wii, so they could afford to keep this gen going longer than Sony cold.
2011 follows the existing pattern of five year generations. It seems like the natural time period. Though 2012 has been rumoured as well.
Even if Wii2 was computationally superior to PS3, would we even be able to notice? Is the average consumer going to notice, or even care?
The gap is narrowing. Can you imagine much more than this gen? Sure you could always go to photo realism but who has the money to develop games like that? That's part of why I figure Nintendo wouldn't bother topping the PS3. Nintendo barely pushes the Wii now. Most of their games look like Gamecube titles and not even really pretty ones at that. They'll eventually upgrade their hardware because the adoption of HDTVs will force them to. But it will be third parties or devs like Retro that push it. EAD will mostly crank out stuff that looks like a Dreamcast launch title.
This is all the more reason for Sony to stay put. Where do they go from here? How do you top the PS3 in any significant way aside from doing new stuff with the controller, which they're doing and which would not require a new console? There is concern that game development these days is too expensive. So how can Sony or Nintendo or anyone else take things even further? Who will have the budget to make games that take advantage of hardware superior to the PS3?
This is why we hear rumours of 3D displays. We can't think of anything else. You can only make graphics look so good before it no longer makes business sense. You have to go to somewhere else. And if going somewhere else just involves extra doodads then why not just make it an accessory and keep your existing userbase?
Imagine if Nintendo had literally just repackaged the Cube and included the remote and called it their next console. I don't mean this 1.5 Gamecube thing I mean if you opened up the machine you would discover that it was actually the EXACT same hardware only with a new controller and some sort of chip or something that just "unlocked" Wii games so that you couldn't just put Wii games in your Gamecube. In other words you could actually mod a Cube to play ALL Wii games. Would you not feel ripped off? If new doodads are the only direction we can go in now then that's what it would be to release a new console. It would be that kind of rip-off so they might as well make the doodad an extra.
I think we're reaching a point where hardware will just stay put. At some point it will do to the law of diminishing returns. Even if some company tries to keep pushing in new console it will become harder and harder for them to come up with something that people will feel the need to upgrade to.
