Crackdown 3 Exists in the Cloud

I rag on Microsoft quite a bit.  But this demo for Crackdown 3 is pretty incredible.  Basically having the physics you've always wanted in an action game.  It also completely eliminates any sense of a game existing only on your machine.  Because no one machine could ever render all this in real time.  I'm pretty sure that last part is a very intentional twist on Microsoft's part.
