Major Xbox announcement coming tomorrow?

"Word on the street (that is, Gamertag Radio) is that a major Xbox announcement is dropping tomorrow, set to coincide with the final round of the Pac-Man World Championship. Microsoft's Aaron Greenberg dropped the hint via an instant message session with GTR's Godfree. What the hell is this announcement about? We have no idea, only Greenberg's cryptic words, 'we have a secret unveil for gamers around the world that I think will go down in video game history.'

What in the world could it possibly be? Does it have anything to do with Ignition, Microsoft's new music initiative? We've contacted Microsoft to see if we can dig anything up, and we'll let you know as soon as we hear anything."
