I don't think so. His description was that it was speeder bikes in a forest, like Return of the Jedi, but it was mostly a demo of the graphics capabilities, not a complete game.

e.g. I remember he specifically said you could fly in any direction you wanted, but there was a wall at the edge of the forest, as opposed to it wrapping around or having a non-inmersion-breaking reason for being constrained to the one area.
