No there's obviously not going to be someone breaking protocol over at Microsoft as our queries to the giant have turned up rather would you'd expect.
Microsoft "do not comment on rumour and speculation", and the idea of Xbox 360 titles on PC with Windows 8 is super rumour and extreme speculation.
.
Having PC and Xbox become one is a great move and would help BOTH platforms and allow M$ to address the entire XBL demographic at once. I doubt anyone would have one without the other especially as M$ is ratcheting up the features like Skype integration, Windows Phone 7, and of course all the games, movies, music, ESPN, UFC, Skype...etc
This is about world domination for these guys and this kind of stuff really get the analyst mouth watering. M$ is moving like a Bear with a bee sting. Deals with R.I.M, LG, Facebook...you name it, it's war with Apple and Goggle. Something big is coming down the tracks and right now the light is blinding.
Nothing motivates you better than when it gets personal. Somebody got personal with Stevey B at M$. These guys a rolling like thunder right now.
Isn't it exciting!!!
That way all Windows 8 based laptops & pads & desktops & Windows 8 based phones can play Xbox 360 games without worrying about the requirements and any mobile device will become a direct competitor to Nintendo DS & PS Vita & off course the iPhone.
and the last but not least the piracy issue (excuse) solved.
