Im backing MK, On the gamecube double dash sold a heap and by the time MK is released the wii will have passed the gc lifetime sales.

i think MK might win but it will be close

Are you talking hardware or software sales?
Hardware; GT 5, games seem to have little effect on hardware sales for the Wii.
Software; Tie, Wii has the install base, but GT is a massive title all over the world.

Mario Kart will beat it.

i'd say mario kart, but GT will do well for itself

I think it is so close here, it will come down to which game is the better game.

You heard it here first. MK will trounce GT in overall worldwide sales. Yes, GT5 will do great, but MK is a staple on the Wii. It will have one of the highest attach rates in console history. There's my John Lucas for the day.
