The media are posting what they learn, and are told. I'm delighted to see a pro-active, determined source of information to cover these kind of events. Microsoft are the ones left lit up, caught holding the spade.
Even the title of the event was puzzling in light of what we saw was present:
"Xbox: A New Generation Revealed"
What other impression were people supposed to draw, with that in the TV (tv, tv, sports, tv, television...) guide? Microsoft judged things really poorly, and it's unexpected given the pre-prep, and the fact that they were in full control of the event - if then seen to be in no control whatsoever of what took place following.
