Call of Duty fanboys be prepared to get your Xbox Live downloading fingers ready this weekend, because Activision is set to premiere a brand new Call of Duty: World at War trailer via Xbox Live this weekend.

A new World at War game trailer will be available for download exclusively from the Xbox Live Marketplace beginning Saturday, June 21st and will be available until Sunday, June 22nd. So, we advise hopping on the XBLM sometime during your ritualistic Saturday morning cartoon viewing and Lucky Charms eating to download the latest glimpse at what Acti has planned for the CoD franchise. Here's to hoping World at War knocks our socks, shoes and pants off.
