Microsoft Interactive Entertainment Business Chief of Staff Aaron Greenberg recently stopped by the Major Nelson podcast to discuss next week's Xbox reveal event and how Microsoft will show its "vision for the future of games."

"We're really going to tell one story across two events. So we're going to start on the 21st and really that's about revealing the next Xbox platform, really our vision for the future of games, the future of entertainment. We definitely have a lot of surprises planned." Greenberg then specifically called out Call of Duty: Ghosts, which will have its next-generation engine demoed during the Microsoft event.

"People are going to get a great inside look at really the making of the new platform and the team that's brought it to life," Greenberg added. "I mean, to be honest it's really about the team, the people here. That's why we're inviting people to campus, we're going to bring them behind the scenes a little bit. We've never done this before and so it's really exciting to be able to do that. But I think it's a lot of laying the foundation - probably the best way to describe it - and then just a couple of weeks later we go to E3."

Greenberg concluded that more will be shown at E3 and after, leading into this holiday season. "E3 is all about the games. At E3, I mean, if you're a gamer, it's going to be tons of exclusives, world premieres and obviously even beyond that we have a lot to share between then and this holiday."

The Xbox event takes place on May 21 at Microsoft's Redmond campus, located in Washington state. Be sure to have your browser locked to Joystiq starting at 1pm ET (6pm GMT, 10am PT) for all of the scoops, commentary and neatly organized words you've come to expect.
