Note: this list is only for home consoles.

Number of games in the top 20, by system:
Wii: 7
Xbox 360: 6
PS2: 4
PS3: 2
Xbox: 1
Also note that Wii Sports is not included in this list. The list also confirms that Wii Madden did comparatively poorly, as Ioi predicted. I'd also wonder how -- or if -- the Warhawk online sales were included.
