Sony really fucked up with the design of the PS3.Do you guys not realize that the PS4 can't emulate PS3 games? This is why I'm surprised people are always pissed at PS3 remasters...like you realize that's the only way those games will be forward compatible with PS4 and PS5, right? The goal should be to get as many classic games running natively on PS4 as possible, because that's the only way those games will be forward compatible in future generations outside of ports.
Even their servers today are PS3 hardware, something like 8 PS3s on each server blade. If it were possible to emulate the PS3, they would have done it on the server side at least.
