I want to see How Nintendo/Developers are going to use this to enhance game-play and Not make it feel tacted on because to me I cant see how this is going to change anything 

I really hope that they end up using this. I can't wait to play advance wars with tiny little planes appearing to hover above the screen.

There are a few companies that have been working on glassesless 3D technology. Toshiba is the one that jumps to mind, but there are several others too. It's safe to say that Nintendo are working with one of them. But there were rumours of them using a Sharp screen before Sharp made this announcement, so it's looking quite possible that the 3DS will use it.

" I really hope that they end up using this. I can't wait to play advance wars with tiny little planes appearing to hover above the screen. "

With all the "hovering" talk going on, I just like to mention that I am much more interested in the depth of field behind the display than in any fancy "reaching-out" effects.

That mock is impressive.

Well if the big N do use these screens then that'll be cool, I guess. Though it'd go against reusing cheap, old and unfulfilled technology to good effect in a new console like they seem to love doing. I mean the GBA was hardly cutting edge, the Wii is just a GameCube that's been juiced up, and the DS uses the same ARM processor that was in the original N Gage, or something. Not that I don't love my GBA, GC and DS, that is.

That is quite an impressive mock up but how small must your hands be to hold that thing?

I have a weird feeling that mock-up could be very close to the final product.
 
Just sayin.

" That is quite an impressive mock up but how small must your hands be to hold that thing? "

I suppose so yeah, It still looks a bit unwieldy in "DS Mode" but that does not take away that this is a very impressive mock up.

" I really want the 3D handheld to work, and if I trust anyone... I trust Nintendo. They think outside of the box. I'd also love for 3D technology to work with glasses because I'm in need of regular glasses, and I really don't want to wear two pair of glasses. "

Woah the tech works both horizontally AND vertically oriented? How do they pull that off? With both horizontal and vertical pixel angle correction that changes dynamically based on orientation? If so then it needs a camera to sense where your face is and adjust the angle accordingly.

Another mock design, this time by a Frenchman:
