Numbers by console producers are usually bullshit. I remember what they said about PS2 before launch and what were in fact the actual games, so let's wait for the real thing, that's the best we can do.

About the PC vs console debate it's really down to which kind of games one wants to play, power doesn't matter actually. If I want to play the next Zelda or the next Resident Evil or the next Gran Turismo - whatever - I will keep playing with my console. The same goes for the fans of RTS games, or Doom addicts, they'll be happy with their PCs. Horsepower really has nothing to do with this kind of choice.
