PAX begins tomorrow and it's possible we could see a big reveal from Microsoft. Specifically, there might be a new Age of Empires unveiled.

At some point last night, a folder entitled "Age of Empires" was created in the press directory of Microsoft's outside PR firm (via GMR FM). There's nothing in said folder yet, though. PAX runs from September 4-6 so perhaps it'll be filled with screenshots and movies of some glorious new AoE game during that period of time.

The historical real-time strategy series was developed by Ensemble Studios, who closed down earlier this year after they finished work on Halo Wars. Microsoft formed a new studio with some of the Ensemble staff called Robot Entertainment. If a new AoE was incoming, one would expect Robot would have something to do with it.
