Microsoft announces the debut trailer for Call of Duty: World at War will show up on Xbox LIVE Marketplace June 21-22. On a related note, Spike TV announces GameTrailers TV with Geoff Keighley (GTTV) will "unveil an exclusive first look at in-game footage" from the next Call of Duty game as well, though it's not clear if this is the same clip as on Xbox LIVE. They say the show will air "Friday night, June 20th, at 1:00am ET/PT in HD." Not to confuse things, but that actually means early Saturday morning June 21st at 1:00am ET/PT.
