Hmm... historically the amount of 10M+ sellers has been:
NES: 3
Gameboy: 6
SNES: 2
GBA: 2
N64: 1
PS1: 1
PS2: 4
DS: 5
Gamecube: 0
Xbox: 0
The Wii already has two bundled titles above ten million and totally up yours if you wanna count them, but I think there will be 3-4 other titles getting there eventually. At least 2 of them won't have a name that starts with Wii.
It looks incredibly unlikely that anything on the 360 or PS3 will make it to 10 million. Probably 2 or 3 360+PS3 multiplats, but definitely no exclusives.
