ClickyAccording to a recent patent filing Nintendo is looking to incorporate motion controls into it's next handheld. We've already seen this with games like WarioWare:Twisted, and a Kirby game of yesteryear that I can't remember the exact name of, but personally I'm not too excited.
I'm hoping the DS2 is just that, 2 screens, one (maybe both) a touchscreen, bigger screens than the DS1, same button layout with a decent analog stick, but perhaps it would retain it's D-pad for left handed controls, better graphics, and get rid of the GBA slot in favor of a GCN slot!
For me that would be ideal, hopefully this patent is just a test idea that will fail with it's test groups.
