Well MS is going to go cloud, but first will be building its universal service and they need to build a competitor to steam on pc. Problem i see if that no one will pay for this service on pc when there are many free alternatives. And how would they justicify charging the 360 people when pc get it for free, but then they cant charge the PC people because majority of the content they offer is either free or cheaply available few short clicks away.
Also the windows phone for PC, i dont know. Windows 7 is fantastic i dont see the need to radically change the famous UI.
Of Course That's Just My Opinion, I Could Be Wrong
