I can see myself getting the PS3, but only cos they're releasing FFXIII on it. I can't stand not having one of those games.
Never played FFXI cos it was online only. But have all the rest.
I always loved my PS2, and still play it, so I would imagine doing the same in a few years time. I'm sure Sony will re-release the PS3 again, with backwards compatability as they're bound to receive some negative feedback on their 40GB versions.
