ignoring that PS3 doesn't have BC and this is the way for non-early adopters to play their PS2 games, by buying them again, I like that these games are available digitally. Hell, if the Vita wasn't a dumping ground, I'd guess these might be playable on that someday.
and if true, $9.99 is a fair price, but that's likely the bottom end. PS1 games are either $6 or $10. If Dirge of Cerberus is ever on PSN, i'm guessing $15. I think Xbox games were $20 on XBL and maybe dropped; I quickly checked and Halo is 1200 points (=$15?). Virtual Console has no account and N64 games are $10, but that's Nintendo.
