this just in: Xbox 360/PS3s gameplay value outdated by november 19 2006. i feel graphics have some importance, but when it comes down to it they cant cacel out gameplay. if graphics were the big thing then we would not have videogames today because the NES and such would have bombed miserably. the wiis gameplay is something microsoft and sony will never be able to touch with any advanced graphics. but i think your right, an advanced form of the wii could be out by then. its hardly unthinkable, they already talk about the "Wii2" or whatever they call it.
A delayed game is good someday, a bad game is bad forever.
