I'm guessing GoW 3 will be on a DVD instead of a CD...?
Anyhow, shouldn't be too much of a problem with software like Nero.
I'm not encouraging you to break platforms for two reasons though:
1. It may very well be illegal (in fact, I think it actually is, EULA's aren't very forgiving for this sort of thing)
2. It's going to suck. The game is PS3 optimized, won't support any kind of noteworthy resolution and won't have any kind of decent support.
