Infinity Ward spells out Modern Warfare 2 voice cast

Another voice work announcement from Twitter now, as Infinity Ward's Robert Bowling (aka FourZeroTwo) has confirmed that the cast of veteran voice actors has completed recording its grunts and grumbles for what seems to be the only game coming out this holiday, Modern Warfare 2. Roll credits:

• Barry Pepper (Alex Mercer in Prototype and an amazing sniper back in WWII)
  
• Kevin McKidd (Dr. Hunt on Grey's Anatomy and not something on the McDonald's menu)
  
• Craig Fairbass (Gaz in COD4 -- recently thrown off a mountain in Cliffhanger)
  
• Keith David (Voice of Goliath in Gargoyles and host of sex parties in Requiem for a Dream)
  
• Glenn Morshower (Played an agent in 24 and moonlights as a Jim Gaffigan lookalike)
  

Fairbass is almost definitely going to return as the voice of Gaz, but the others actors have yet to be matched to the game's characters. Best guesses?
