Xbox just released they are making lists for backwards compatibility. So just cuz it's not now doesn't mean it won't be. PS already said they have no future plans for this whatsoever. You already have a live account so all that switches. As for your saves, we best thing I can tell you is get an external hard drive for that and save it all on there. Sony is a hardware company, they do the best processors and such, but Microsoft is a software company, everything links with it. Computer and so on. I've always been an xbox guy even though none of my friends are, and I'll never look back.
