Being realistic, ask people that don't go to Gamespot and you'll find out.
Actually, the internet says "it's a feature many people request, but few people use" :P
Imagine not wanting your legacy titles playable on the latest hardware, either through backward compatibility or digital purchase.
im disappointed that sony didnt make 2d games illegal like they did in the ps1 era. :(Sorry, but I only play new AAAA games. I don't have time for 2D games from the PS3 era.
PS3 might not be that difficult. If a bunch of random people doing it as a hobby can get games to boot, a company with access to schematics and code working full time jobs should be able to do it."but no one cares about backwards compatibility"
I really hope sony gets around to it. PS3 might be difficult but ps1 and 2 should really happen
