am not convinced by the supposed PS3 game streaming on the PS4. Unless they have magically found a way to get rid of terrible input lag
It's called "a good internet connection".
I've played a fair amount of games via OnLive and I really didn't notice the input lag after a few minutes. People act like it's only usable on like... turn based games where there's no need for precision. It worked fine on games like Borderlands for me.
