We haven't figured out a way to travel into the future yet, and we're just as upset as you are about that. But the closest thing has to be playing games that aren't actually out yet, right? Microsoft is offering PAX East attendees a chance to do just that next weekend.

Major Nelson posted the list of activities and upcoming Kinect and XBLA titles that will be playable at Microsoft's booth, including Trials Evolution, MineCraft: Xbox 360 Edition and Steel Battalion: Heavy Armor. We hear one of our editors really liked that last one when he got a chance to play it earlier this month.

Also of note is a playable build of Dust: An Elysian Tale, the winner of 2009's "Dream-Build-Play" competition. It's currently slated to launch on Xbox Live Arcade in 2012.
