This is an obviously fake video showing some kind of holograms, but imagine the new 3DS could do this. The images would stick out just a little from the screen (half inch?)

OR, it will be like this? The DSi is already doing this with a game, so I doubt that this is the "3D" the new DS will bring:

I'm looking on youtube to find a demo of the tech that the new 3DS will have, but I can't find it :x

The 2nd video is cool!
I hope it's something like that!

yeah looks cool but the DSi is already doing that.

It wouldn't be much of an innovation....

The first one was pretty funny =)

That video looks pretty good. Where did it come from?

@ mistic wolf

that's a DSiWare game I think...

Its just using the tilt to move the camera. That is so boring.

if it was like the first video i would die...

probably won't be though :p

Hopefully it'll be more like the DSi game that already came out (linked above) but with more gameplay based enhancements. In other words, Nintendo has actually found a way to tie '3D graphics' to the gameplay. And not just make it a simple graphical enhacement of the graphics.

And knowing Nintendo, this is probably what they'll do. If I was to imagine a simple way to alter a '3D effect' to improve gameplay, especially with a touch screen, it would be such things as the 3D image being altered based on where you touch the screen and based on pressure sensitivity. Or a 3D image on the screen moving based on your field of vision. In other words, that '3D effect' will just be a 'third addition' to the gameplay where touch and normal controls were originally two imput controls.

It's not going to be like the 1st one. For images to physically 'pop out of the screen', they'd have to be holographs. Which isn't going to happen, for obvious reasons, lol.
3D images only convey the ILLUSION that the images 'pop out' of the screen, but really don't. My guess it's something like that, and not like the stuff shown in the 2nd vid, or that DSi game Bamboleo posted a vid of. 'Cos obviously, that can already be done on DS. No point in bringing out a whole new machine for that, and call it '3DS' on top of that, haha.

Anyway, between the 3D, the dual screens, touch sensitivity, the improved graphics, battery life and wireless stuff, the rumble screen, and the rumoured analog stick, as well as probable tilt and/or motion sensing, it's going to be EPIC.
