Which Game Console Has the Most Games?

Which of these game console can play the most games? Wii, PS3, or Xbox360

Suggestion:

I believe the Wii has the most games, but take it for what it's worth. A lot of the games are crap because less talented companies are taking advantage of the Wii's popularity. They produce nothing but crappy games hoping that uninformed consumers would buy their games thinking that it's similar to Nintendo's games.

The PS3 can play the most games because it can also play PSX games. The PS3 with 4 USB can also play PS2 games in addition to PS3 and PSX games.
