so, how does the controller work you ask? just, motion sensitive. the same system as with the PS3, if you move the controller, your character or the device of your caracter will move in the same way. you'll still have a controller, and some buttons, but motion sensitive's something of the future, so i guess they all installed one for the next gen consoles.
and the new zelda game on the wii looks good, really. the graphics are a lot better then i'd expect, but i doubt i'll buy a wii, from what i've heared of the E3, it seems it's still quite difficult to use such a controller.
