Following yesterday's announcement, 3D Realms has released the promised Duke Nukem Forever teaser trailer!. According to George Broussard of developer 3D Realms, the approximately minute-long video was originally created internally for the purpose of holiday festivities and marks the beginning of further media unveilings surrounding the notoriously long-in-development first- person shooter.  The clip includes gameplay footage, Jon St. John returning as the voice of Duke, and the music of game composers Jeremy Soule and Julian Soule. It runs around a minute and ten seconds and is available in five variants, covering 720p and 480p resolutions. Mirrors: AtomicGamer, CGO, FileFront, GameTrailers, GamesFire, GH, PixelRage, Primotech, VE3D.

"The release is still 'when it's done,' but you can expect more frequent media releases and we're not changing engines again and we have considerable work behind us," Broussard told Shacknews today when asked about a release date. Platforms for the game were not confirmed, but when asked today whether Xbox 360 in addition to PC is likely, Broussard's response sounded positive though not definitive. "I don't think we've stated that yet for the record but your observations are probably noted," he conceded.
