Over at the Geoff Keighly blog, he reveals what will be in the upcoming episode of GameTrailers TV, and it will be big.

They will have exclusive multiplayer and single-player gameplay of Gears of War 2 right before the Xbox breifing as well as debut a new multiplayer map. Then, they will show us a sneak preview of the E3 trailer for Fallout 3, one of my (and probably yours) most anticipated games this year. Then they will show more on ThatGameCompany’s upcoming PLAYSTATION Network title, flOwer. Rock Band 2 will then take the stage as Harmonix debuts the gameplay footage with one of the game’s songs. Finally, to end Friday’s episode, BioWare will debut their new unannounced game on GameTrailers TV in trailer form. They will also have another trailer as well, but they won’t tell us more about it until Friday night. Get excited, because that is only the start of their E3 coverage.
