It could prolly play regluar Wii games in HD (most in 720P while some in 1080P), but can it play Gamecube games also? (in HD or ED/SD)
If it won't play Gamecube games, they'll probably make some of them available fer download on the Wii U's shopping channel.
Speeking of VC, along with adding GOOD titles (not crappy horses#!t), they could also add Sega Saturn, Sega CD/32X, Atari Jaguar, 3D0 (Maybe), and Sega Dreamcast stuff on there if Ninty gets the proper licenceing to do so.
If they put stuff from the Philips CD-I on (like Hotel Mario and the horrid LOZ titles... among other shitewipe titles), some ppl (like me) will freek!... While others (hopefully not) such as the Youtube poopers may jump and jizz their pants in joy.
