Will the Playstation 3 dominate the Wii?

[WiiRHardcore]

I remember before the Wii came out, someone at Microsoft mentioned that the Wii would make a great second console to the 360. So if all of the 360/PS3 owners also bought a Wii, by the end of this generation the Wii could outsell the 360 and PS3 combined. It's pretty close so far,
Wii: 20.64
PS3/360: 26.33
