You can use the wii controllers for multiplayer. You just can't use more than one wii u controller.
yar, but if new developers are all jazzed to create a game for the system, it's now essentially asking them to create two.
for example, if tekken makes this great new fighter using the wii-u controller, all that goes away when you invite a friend over. now either one of you is using the awesome controller and the other the older one, or you're both using the older one. ...or, there's no "traditional" in-home multiplayer, at all.
