that doesn't make any sense at all...Plus built in homebrew support so having to get carts and thus risk piracy wouldn't be necessary...(even though I LOVE all my free games)
Anyway, an analog stick is what the next DS needs most...although I can imagine that Nintendo is never going to add an analog stick to a handheld system for portability reasons
And since it's cheap and easily implemented, what would be a DS2 without motion/tilt controls? that way, Nintendo can fool the customers into thinking they'll get a portable Wii, probably making it an even bigger success than the DS Lite...
think about it: God of War: Chains of Olympus (a PSP game) already looks as good as most Wii games, and that game is for a 3 years old handheld...now imagine a new handheld that has the same graphics as the Wii (which the DS2 probably will), as well as motion controls AND a touchscreen... it's like your favorite system and your favorite handheld combined...Nintendo would be nuts not to include motion controls
I personally hope that Nintendo will ditch the GBA slot in favor of a smaller casing...few people will be interested in GBA compability as long as the DS2 supports old DS games, and only very few DS games/peripherals made use of the GBA slot (Opera Browser, Daigasso Band Brothers, Arkanoid DS, Megaman ZX, some games with rumble support...)...who needs it, really?
if the DS2 has a built-in rumbler and internet browser, the GBA slot will be even more useless...what about an SD card slot instead?
that's pretty much all I expect from the next DS, features-wise...hardware-wise, I expect it to be slightly more powerful then the PSP, but with better battery life
