It never really showed that its running on a ps3. It just shows the screen. Might (probably) just be fake.
That's recommended to be able to use XP. And then you can't even use stuff like IE7 and WMP11 normally.
Other then that, a PS3 can't even use Vista at minimum. Just shows, PC PWNS.
And if I'm not mistaken the GFX card for both consoles are equaled to DX9, not 10. So again, as far as graphics is concerned PC PWNS. And for a console that relies on it's power that quite a bad thing.
City in the Sky sucks
