PS1 and PS2 are just software and legal issues. Would be cool if they end up being in there.why?
PS3 might be hard. CELL was funky cool. How well do PC emulators handle ps3 games?
if BC included discs how could playing the game the customer purchased cause a license issue.
more likely, if BC was only for digital download then the the only supported software is the software that publishers choose to publish to psn. the entire backlog won't be there (like on xbox) but a decent amount of publishers would probably be on board with more money,.. especially if it is sony doing the compatibility testing which is what I think MS did.
