During an interview with Sony lead system architect, Mark Cerny, he said the that PS4 will have the strongest launch lineup in PlayStation history, which has been said many times. The accessibility improvements for the PS4 are about as easy as PC development. This will make things easier for the developers to port a game engine from the PC to the PS4.
“The launch lineup for PlayStation 4–though I unfortunately can’t give the title count–is going to be stronger than any prior PlayStation hardware,” Cerny said. “And that’s a result of that familiarity.”
Cerny also emphasized the different ways that Sony is “supercharging” the PC-like architecture in the PS4. This will benefit the developers a lot to port a game to the PS4 more quickly.
