Pundits are insisting that games consoles are headed for doom.
i actually think that is where MS is going... buy once play anywhere... one cloud, 3 windows remember.but either way i'm sure it wont be the heavy titles like halo n w/e that will be cross device... it will be more the XBLA games, sonic, fruit ninja etc etc... dont expect to see gears of war 3 on your mobile device.
Have you seen Dead Space on android? I connected my phone to the TV via hdmi and the graphics and gameplay are indistinguishable from an xbox.
