We didn't have to wait long for footage of more of Rhythm Tengoku Gold's games after the three-game E3 demo. Nintendo has posted seven short commercials demonstrating gameplay. The YouTube video above collects six of the commercials; to see the other one, you can check the website, although (spoilers!) it's just footage of a metronome anyway.
The celebrities in the videos are almost as interesting as the gameplay videos themselves -- the Japanese Steven Tyler in the pink suit (actually Toshihiko Takamizawa from the venerable Japanese rock band The Alfee) is quite a departure from the indistinguishable idols these companies normally use in game commercials.
If that's not enough Rhythm Heaven for you (it isn't), the Japanese site has also been updated with new screens and control diagrams.
