During an interview
with Sony lead system architect Mark Cerny, he said the that PS4 will have the strongest launch lineup in PlayStation history. This has being said many times the accessibility improvements with the PS4 is about as easy to develop for as a PC, which 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."
