One of Sega's biggest booth attractions at E3 is a fifteen-minute reel of next-generation footage. While all of the footage shown is either confirmed for Xbox 360 or undecided, the sequence ends with a lengthy teaser for a new Sonic game. Since Sonic has been consistently well-received on the GameCube, it will most likely appear on the Revolution (though it was clearly running on an Xbox 360 alpha kit).

The Sonic teaser is almost completely a cut-scene showing off smooth, real-time renders of Sonic dashing through a meadow and evading huge armies of robots. To prove the footage is generated on-the-fly, the camera briefly goes into first-person view and the demonstrator shoots rings. The demo ends with Sonic turning into Super Sonic and flying into a mass of enemies.
