The free event will once again host developer talks, tournaments and a giant 'Bring Your Own Computer' LAN. Further details are due "in the coming weeks" though CEO Todd Hollenshead promised last year that id would reveal more of Doom 4 at QCon 2010.
Bethesda's involvement in QCon 2009 included the first public showing of Brink--which it is publishing--and a presentation by Bethesda Game Studios executive producer Todd Howard. It's highly likely that Fallout: New Vegas will be on show in some form this year.
The Hilton Anatole hosted QuakeCon from 2006 to 2008 and was due to be invaded by rampaging geeks once again in 2009 before id switched venue to the Gaylord Texan.
However, a shadow hangs over one customary component of QuakeCon. The maker of energy drink--and source of countless jokes that are no doubt hilarious--Bawls has entered restructuring to cut costs and possibly prepare the company for sale. It's yet unclear whether this will affect the traditional Bawls Chugging Contest.
