Nintendo 3DS Press Release...

One of my friends said Nintendo wants to bring back their domination on the 'headache-machine' market. As far as technology, 3D screen technology(ie without the glasses) has been around, and it won't be super thick either. The only problem that keeps if from domestic use is that in order for it to work without glasses, there is only a certain distance you can be from it before it starts to lose the 3D effect. Most home televisions put their TVs any random distance and orientation in their house, nullifying the 3D. With a handheld, it is much easier to pick and enforce a distance from the eyes for the 3D effect.

Like with the DS, Nintendo will be forcing its developers to use some functionality(3D) along with the other functionalities(dual screen, touch screen). Some publishers might complain a bit, but it prints money, right?

They're quite possibly using the DS game cards they are using now so I'm a little worried about pricing and how much improvement is in the graphics.

I think the Nintendo 3DS will use a different cartridge than the DS, but there will be a slot to fit the DS games. The DS Lite cartridge was different from the GameBoy Advance cartridge, but there was a slot to fit the old GameBoy Advance cartridge. The new 3DS will probably be similar in that aspect.

If they are using a parallax-barrier screen, I'm just concerned about the "sweet spot" you'll need to sit in. I don't always hold my DS in one exact spot.
