Activision announces Call of Duty XP 2011, a gathering of Call of Duty fans in Los Angeles on September 2 and 3, calling this the "ultimate fan experience" for the military shooter series. Tickets to the event are $150.00 USD each, with 100% of the ticket sales being donated to the Call of Duty Endowment, a non-profit charity that helps veterans transition to civilian life. The event will feature the Call of Duty: Modern Warfare 3 multiplayer reveal, live events, and a $1 million tournament. Here's more: "Attendees will be among the first to have the opportunity to get hands-on time with multiplayer and the new Spec Ops survival co-op mode. Also on display for the first time will be the full feature functionality of Call of Duty® Elite, the innovative new online service, built from the ground-up to support Call of Duty: Modern Warfare 3." However it does sound like the XP in the title is about as close as this is coming to involving Windows, as the event's lead sponsor is Xbox 360, and they say: "Supporting this epic reveal is a series of real-world Call of Duty action-experiences and gaming competitions as well as an unprecedented $1 million Call of Duty tournament by Activision and the event’s lead sponsor, Xbox 360." Here's word:

Tickets will go on sale 19th July, giving attendees a two-day pass and the chance to be completely immersed in the action and excitement of Call of Duty. Players will be able to challenge each other in a paintball firefight on a life-sized Call of Duty multiplayer map, as well as attempt to speed-run Call of Duty: Modern Warfare 2’s legendary “The Pit”—for real.
