Despite the booming success of the current Nintendo DS lineup, it is inevitable that the DS train will run out of steam and the big N will be forced to release their next big handheld. At GDC, much speculation arose about the new Nintendo handheld including rumors about capability and release date.
The rumors center around the accelerometer functionality expected to be in this new handheld. Developers that wish to not be named have been reported as saying that it has iPhone like functionality but is apparently much better. The main features are a bigger, higher res screen (unknown if it’s going to be larger than the soon to be released DSi XL), a smaller gap between screens and more powerful processing power.
Perhaps the most interesting rumor of all is that it will be released this year. Of course, this may be just wishful thinking but I believe that if its true it would definitely show at E3 this year.
