Last month, Spike TV executive producer Geoff Keighley revealed that this year's Video Game Awards (VGAs) would play host to a number of big game announcements, from Metal Gear Solid: Rising to Microsoft's next instalment of Alan Wake.

　　It now appears that Keighley wasn't done teasing all the 2011 VGA news. Last week, the host of this year's awards offered up yet another tasty morsel via Twitter, declaring, "Yes, at VGAs we will be revealing a PS3 exclusive you won't believe. We'll be able to share more soon."

　　Since then, Keighley has followed up with another two Twitter posts about the new title: the first promising to stoke speculation, and the second linking to a teaser site for the new game (with "Last of Us" apparently the name of the game or the teaser campaign) and reconfirming that the game would be revealed live during this year's VGAs.

　　What will the PS3 exclusive be?

　　The teaser site currently features two clips. The first shows real-life news footage of civil unrest and rioting, with a voice-over hinting at a US-centric point of view. The second clip, shorter than the first, simply shows footage of an insect in its natural habitat and does not feature any voice-over.

　　This year's VGAs will feature announcements surrounding Metal Gear Solid: Rising, Alan Wake, and BioWare, with the EA label slated to show off a new game from a new studio at the event. Last year, the awards featured reveals of The Elder Scrolls V: Skyrim, Prototype 2, Mass Effect 3, Insane, and SSX.

　　The 2011 VGAs will take place on December 10 and will be broadcast live on Spike TV and MTV2, beginning at 8 p.m. Eastern, 5 p.m. Pacific.
