This whole backward compatibility is in my opinion getting way too much attention. I have both PS2 and PS3 and frankly speaking I have not used them at all this year anymore! There are just so many good games for PS4 available. I support bringing some of the best games of previous generations to new players who do not have the old consoles and have not had chance play them, but I think remastering is the way to go. After all the old titles have to compete with tons of really good new games, so they do need some fresh look to get attention. Finally, there is often arguments that why should people pay twice for the same game. Well, if you have the game already, you likely have the old console too, so why would you want to buy it to new gen?
