IMO there's no need for a PS4 for a very long time to come. Core technical reasons Blu-Ray and the Cell processor.
Game engines can be greatly improved on further taking better advantage of the above mentioned technologies, the firmware must be improved gradually as well and maybe some hardware redesigns with new default features would be nice. But the core technology is very solid for a very long time to come.
