Wii and DDR?

Nintendo demonstrated a Dance Dance Revolution-like game at E3. That would be totally awesome. The game where you kick soccer balls while avoiding things being kicked at you sounds like it might be pretty fun and silly! It looks like there could be some fun games for me on the console. Now I just need to persuade the tomcat to leave his Wii with me permanently. And they need to release a new version of Elebits...
