please add internal rumble. I would also want dual/multi input touch screen

It needs a bigger 3D screen.

I would like both screens to be the same size. Wouldn't rumble eat the battery up too quick though?

GBA slot and support please?

Yeah, it would be a big drain.  Not to mention that they tend to break easily, so it's not as simple as replacing a controller.

I just want the thing to NOT look like a Nintendo DS, which it still does.

That's one thing that I've always looked forward to when it comes to new Nintendo hardware.  It physically looks and feels different from previous hardware.  3DS just physically looks like a DS with two camera lenses on the top.

What does it matter what it looks like? Why fix what's not broken?

That's the thing, though, man. The DS Lite is kinda uncomfortable in my hands, and I don't even have very large hands.  I would just like an aesthetic change in design, that's all.

I know it would up their production costs a bit, but I'd appreciate it if the bottom screen were the same size as the top screen.  It just looks odd to not have that symmetry on 3DS.  Having two of those sliding pads would be nice as well for possible future dual analog-type games (honestly, I'd rather have analog sticks, but since this is a flip-top handheld I guess that's not possible).

Ummm...no.
Though a VC-type service is not out of the question.
I also would like both screens to be the same size.  My guess is they are saving money by continuing to use the same screen as the DSi so they can make a bigger profit. Changing to a widecreen touchscreen, while not a big change, would still make less profit for them so I don't see it happening.

Here's my dream revision:

- Big ass Top screen.
- Dual Analog.
- New looks, these ones are meh. To DSish
- Better placement of L & R. Its to hard to use those buttons on the DS.
- Rumble (let me make my own choice about how much battery I waste), just allow me to turn it off.

I'm with Rachtman.  I think back to the glory that is the GameCube controller and I miss that kind of form fitting design.  We're stuck in a nightmare of rectangles with Nintendo's designs and I wouldn't mind them taking a shot at making a more ergonomic 3DS.

However, most will call anything but sleek rectangles "ugly and dated" so they can't really win.

Hardware
Larger 3D screen on the top OR touch screen the same size as the current 3D screen on top.
Also atleast 8GB of internal Flash memory and a minimum of 256MB of RAM to help out applications other than games too.
Concave the top lid so that it has a lip that closes flush with the bottom when closed like the current DS
3D camera on the inside too.
Bluetooth & USBmini (for managing internal and SD card memory)
Release in those beautiful pearl based colors you showed at E3


Software
Background OS that's games and software run within.
Multi-tasking, like background downloading and idle updates
Account log-in w/ friends list - NO GAME BY GAME FRIEND CODES
Downloads attached to account - not system
system attached to account - gotta log in to use online (prevents theft)

It's gotta be appealing and not look like a toy. It's also gotta fit in your pocket or purse.
You want people to want to take this out in public with them and not be embarrassed to pull it out and use it.

I don't think they could make it more ergonomic without sacrificing portability.

Maybe something like the DSi XL, a separate larger model with bigger screens and a more ergonomic design, for people who don't need it to be portable.

I dunno, the original GBA was relatively comfortable and just as portable and something like that could be improved on.  It would only take some small tweaks to make it feel a bit better I think.

Through in a matte finish like the DSi for the 3DS.

Allow me to take pictures from my SD card and use them as wall paper on the 3DS main(upper) screen. Perhaps they could be able to tickered with in 3D.

Make the 3D slider into something similar to the DSi voulume slider and make place it on the lower right portion of the top screen. I just worry about the slider getting broke if I dropped it or wearing out with use.

How would blue tooth and USB mini manage the internal memory of the 3DS?

I want 3DS apps similar, but better than those that Apple offers on the iphone.

I can not say this enough, Nintendo, gives us a virtual handheld service.

Allow a movie player that plays MPEG-4 and .AVI and is managable as the music player on the DSi.

Switch the position of the slide pad and the d-pad for nostalgic reasons.

USBmini so I can hook it up to my computer(without having need for an SD card reader) and back-up files or drag and drop music/movies/videos/pics onto the internal Flash or SD card.

Bluetooth so that it can connect directly with peripherals such a headsets or even the Wii.
You can even use Bluetooth to manage data if you have that kind of equipment on your PC.

& DO NOT switch the position of the slide pad.
Do you really want to bump the slide pad on accident when trying to use the d-pad?
c'mon, think about it. Besides, most games are likely gonna be in 3D and primary control will be analog. Slider pad is where it needs to be.

I like having plenty of internal flash memory and an SD card to back it up. I do like the idea of using a bluetooth headset for multiplayer gaming(Call of Duty 3DS?) and also Skype enable communication. I hav e aboput 4 GB of music on my DSi and I could just store that data onto my 3DS's internal memory and use the free space to store movies and TV shows.

The potential for the 3DS is just without end. There is much that Nintendo could with this device that it is just too appealing to pass it up when it releases(November 2010?).

Once again, I have NEVER put a handheld console/portable/whatever in my pocket to carry around.  I stays in my hand... or wherever I'm gonna carry it to. That's just it... I think the whole "carrying it in your pocket" thing is just a farce.  Make it ergonomic in design... form fitting like Pale said. I want a comfy to hold portable from Nintendo... and the DS, and from what I can tell of the 3DS, ARE NOT.  Ugh.

I carry my DS around with me in my pocket.

Well then you've gotta be in the minority, man. 'Cause I just don't see that as being a selling point.  Most I ever carried mine was in a sleeve inside my backpack that I carried around campus during my college years.

I could see doing that while living in a city such as Boston or NYC that requires you to walk to get to wherever you wanna go. But designing a system with sharp angles is such a turn off...

I agree with Pale on the design of the original GBA, too.  I loved the way that portable felt... and definitely wouldn't mind seeing the 3DS take on a similar form.

How was sound controlled on the E3 units?  I hope they get away from sound controlled by a slider.

In fact a set of sound up/down buttons would be great.  Cycle through some logical audio levels.  The same buttons could double for say brightness if you hold down one of the others.  It be nice to be able to adjust brightness on my DS on the fly instead of only being able to do it at the startup screen.

Both of those things are part of the DSi, and given the similarities between the DSi and the 3DS as it was at E3 indicate they're probably still there.

I'd actually be curious to see some data on this. I don't know what most people would be carrying their portables in if not a pocket. Perhaps it's time for a forum poll...?

Well place me in the minority as well, because I place my DS in my pocket as well.

Their purse?

In the rare instances I travel with a Game Boy, that's usually where I put it. I don't like having things in pockets, if my clothes happen to have them. But I've always assumed I was an exception.

My DS Phat is too big for a "normal" pocket, but I used to carry it around in my cargo pockets all the time. I think I might have carried the GBA SP around in any pocket...
