Sony PlayStation 4
The current hot topic in console gaming, the just-announced , is still largely an enigma. We don't know , when it's being released (beyond "holiday 2013"), or even what it looks like.
For now, it's still the next-gen hardware to beat, and what little we do know sounds impressive, with an entirely new system architecture based on an X86 AMD CPU/GPU that should make the PS4 easier to develop for and more flexible (and, frankly, more PC-like).
But 2013 will take the traditional three-way console race and add several new players, all of which may gain a serious advantage by not being tied into the classic living-room console hardware business model.
