So, the PS4 has been announced. Touchpad in the controller, a depth camera, far-reaching social stuff (streaming your gameplay to your friends and such), allowing you to stream (certain) PS4 games to a Vita, and streaming demos and older games via Gaikai.

It sounds pretty good. I especially like how they sidestepped the whole back-compat issue that sort of plagued the PS3 with the Gaikai streaming.

I wonder what's people at Microsoft are doing and thinking after this news. Especially being able to instantly play a demo via Gaikai sounds good. I wonder if Microsoft are planning something similar... they have App-V, and Office 2013 is usable before it has finished downloading... could they plan something like that?
