Rumours I've seen floating about:
Xbox 360 SOC = 100% backwards comparability + more processing power
Runs Windows 8 = WinRT framework (could be huge benefit for PC gamers, since Sony are moving that way too)
Controller is same
If that's true I'm actually impressed.
So if both the PS4 and Xbox are both just PC's with custom hardware, could this mean developers will start creating games with standard PC components in mind and just downscaling them for consoles? If so that would be fantastic, one platform for developers.
