I thought this debate was over already. PC already is dead. Nothing compares to the infinite power of the cloud, which is only on Xbox.
Do I have to spell it out? I-N-F-I-N-I-T-E that means bigger than all the PCs in the universe put together. MS said so.
That's why MS won't be making new kinds of games and lastgen compatility won't hold back new games. Can't improve on infinite.
