DDR and/or Dance Rush for Nex

Since Zumba can track your feet and steps, I think that now it should be possible for a Nex version of DDR to happen. Please Konami, make this happen!

For DDR, the arrows would be present on the screen. The screen could show the bottom half of the camera feed with the arrows visible on screen just so you can make sure your feet are in the right spots. It should play exactly the same way, but with a little more wiggle room as to how much space you have per arrow (allow some overlapping of the arrow targets? Maybe track the leg/foot to see which direction its going in to allow for the overlap without triggering the other arrows?) As usual, nothing bad will happen if you keep your foot down on an arrow. If you need to step on the same arrow again, your foot needs to physically lift off the ground and the camera should detect that you are no longer standing on that arrow so that you can step on it at the right time as indicated by the song.

There would be some fun unlockables like backgrounds, dancer characters, songs, and challenges.

As for Dance Rush, this looks like the next evolution of DDR. Haven't seen it in person yet, but I think it could also translate well for Nex.
