MS does a Scorpio reveal which is actually "Absolutely nothing"... but gets the fans all excited about beating Sony at their own game. But when you pull back the paper you find MS has given people nothing but a broad stroke idea that they haven't even probably developed that far yet (because its 1.5 years out). I can see why Ryan is laughing.
It's the cloud, kinect and project milo level of PR baiting... you think they'd have learnt their lesson, but people still lap it up.
