On the back of the Crysis E3 2012 presentation leak, here is another one based on the PS4. Again take it with a grain of salt as leaks are just as good as rumours, but we came across it and thought we would post it. So what can you expect from the PS4? Read on…
Sony has been very quite about PS4, much like Microsoft has been around the Xbox720, so the official word that has come out about the PlayStation 4 is that Sony are currently working on the console.
