Architecture change renders current PSN games incompatible with the PS4
The PS4 may have been announced for a Christmas release but we shouldn't be throwing out our old PS3 quite yet if we want to continue playing our favourite PSN titles.
Sony Worldwide Studios boss Shuhei Yoshida has revealed that PS3 PSN games will not be compatible with the PS4.
It's no real surprise given that Sony has made the radical move to ditch the old Cell processor architecture in favour of a more developer-friendly x86 64-bit PC style architecture.
Yoshida added that they would try and make them playable "in some form", which probably means that they will be making them playable using Gaikai's streaming technology at some point in the future.
