Sometimes I think you guys do not want BC, but a remaster for free.
Let's be honest...this is not something MS offers either. There is no level of reworking as Spider-Man will get. Bloodborne will probably be another one to get a remaster too.
Anyway, It's pretty clear Sony will offer some free patches for some games, but it is not their focus.
They are not trying to convince you "Hey, buy this new console to play the best versions of your old games!"
Did they ever say it? Then, who did? Now you know your answer...different approaches.
Meanwhile, Nintendo is selling Mario poor emulation for $60....
