I've not seen a newer chipset Xbox 360 die yet, and FYI, I play my games on both 360 and PC, everyone I know with a PS3 has it sitting there covered in dust waiting for GT5 to come out, since most games are either look better on 360, not to mention the amount of exclusives and the superiority of Xbox Live as a multiplayer service.
The pros really outweigh the cons of the 3RROD etc, xbox 360 games are generally 1080p compatible vs all the PS3 games I've played, not to mention the ancient controller design, the fact that you have to download hundreds of mb of crap to just play the games!
I'd never buy a Wii, I'd get my girlfriend to lol.
