A fighting game was shown off, as was a monster-stomping title, a driving game (complete with pit-stops), as well as offering snapshots of other titles, too.

Steven Spielberg took to the stage to help show off the new system, talking up the full body motion control, which sounds a lot more advanced than the Wii's own pioneering technology.

The director talks of new levels of interactivity, "not a case of reinventing the wheel - but removing the wheel entirely".

One tech showed off full movement; the player hitting balls into targets in order to progress. Another demo was a painting utility - complete with voice controlled colours.

No release date has been confirmed, but we're told kits will be sent to game makers from today.
