The potential reason why the Wii might surpass PS2 sales numbers of 100 million

Again your comparing what should not be compared. Wii is not GC+DS. When you get tired of picking up poop on your DS (which is an amazing feat to make fun,purely genius), you can play a game like SSX Blur or Mario. Those are games you can't do the same on DS. Also no one said there was a Brain game for Wii.
