Nintendo announced the winner of an AOL contest and invited the lucky guy on stage to play a tennis match with Reggie, Miyamoto and Iwata. The game went as you might expect with familiar tennis ball "pop" sounds emitting from the controller's newly revealed speaker each time a player hits the ball.

The tennis game is part of a larger package aptly titled Wii Sports. Footage of baseball and golf, likely from Wii Sports, was also shown. There may be more in the final version as well.

This demo also concluded Nintendo's media briefing. Stay tuned for more news and preview updates later today and gameplay impressions from the show floor tomorrow!
