Upon its announcement earlier this year, the game--coming to PC and Xbox 360 from BioShock 2 veterans 2K Marin--was not provided with any sort of a release estimate.

That changed today, as publisher 2K Games unveiled the lineup of games it will display at E3 2010, listing XCOM as a 2011 release alongside Spec Ops: The Line.

For the curious, we've copied the whole of today's announcement just below:

2K Comes to E3 2010 with Its Biggest and Most Powerful Lineup Ever
Exciting shooters, intense third-person action, authentic sports games and family friendly fare show the versatility of 2K's biggest E3 showing ever

New York, NY - June 9, 2010 - 2K announced today its star-studded E3 2010 lineup that includes premier high-quality games for gamers of all tastes and ages. The full scope of 2K's experience will be on display* in the South Hall at Booth 2823, as the sequels to some of gaming's biggest franchises will make an appearance alongside the debut of new and exciting additions to their portfolio, creating 2K's biggest E3 showing ever.

"By delivering only the hot list-dominating games that we want to play, 2K will take on E3 2010 with its strongest lineup to date across all of its divisions," said Christoph Harann, president of 2K. "The benefit of our strategic approach to this year's roster of delivering fewer, bigger titles -- featuring games like Mafia II, NBA 2K11 and New Carnival Games -- is that we can focus on delivering the most engaging and entertaining experiences for today's broadening gaming audience. From core to casual, 2K will have something for every gamer this holiday season."

In the past five years, 2K has become one of the gaming industry's premier publishers, creating titles that are both critically and commercially successful. By developing a mantra that emphasizes quality over quantity, 2K has published a number of multi-million unit selling franchises in a short amount of time for a wide variety of platforms including BioShock, Borderlands, Carnival Games, Sid Meier's Civilization, NBA 2K, NHL 2K, Major League Baseball 2K and more. This year's E3 lineup personifies the very essence of the 2K DNA of creating prestigious and meaningful titles that continue to innovate in unique and exciting ways.

The 2K booth will be home to eagerly anticipated titles from 2K Games, 2K Sports and 2K Play. In addition, the 2K booth will be hosting photo-ops with six of Playboy magazine's most popular Playmates appearances, further enhancing the partnership with Mafia II that features more than 50 of Playboy magazine's vintage covers and Centerfolds as part of a unique in-game integration. Two Playmates will be present at the booth each day for the full three days as part of the Mafia II Photobooth Experience. Show goers can dress up in period clothing and pose with props and upload their photos to their favorite photo sharing and networking sites. Playboy.com's 2008 Cyber Girl of the Year and Gamer Next Door Jo Garcia will also be available for autographs at 2K's booth during select hours and dates. Furthermore, the 2K booth will debut the official Mafia II consumer demo for hands-on play for all E3 attendees, prior to its release later this summer.
