holy shit, none of the ps3s that are made right now are BW compatible!
good thing mine is the 60 gb version that released in 2006, I think I got the best of everything despite the fact that I only got 60 GB
But to be honest, I dont think I have played single ps2 game on my ps3 since I got it in 2006..
so I would say dont worry about ps2, it is pretty much dead, ps3 games are much better than ps2's , but i can understand if you would want to play some games in the series on ps3.. for example, i am looking for a copy of final fantasy 7 and would like to play it as well (it is a ps2 game) but the 13th is going to be out for ps3
