So, if you wanted your PS2 games on a PS3 you can always buy them again.
As if anyone is going to be that stupid! Download only games is a really bad idea - you can't swap/sell or lend your games and if your hard-drive goes you have to hope you can download them again free of charge! I'll stick to my PS2 thanks
