DDR pads/games/tournament questions

Alright, I don't see anything giving up-to-date detail on it, so here we go! What type of dance games will be played? Strictly DDR? If DDR, Supernova 1/2, Extreme 1/2, etc? I'm hoping there will be Stepmania, or at the very least In The Groove/Mungyodance. Also out of curiousity, what types of pads will be available for play? Trash-bag pads taped to wood? Foam pads? Metal pads? Finally, have tournament ground rules been established yet? Are we going with the traditional "One person picks song, other picks mods" deal?

Any answers would be great, as my legs are itching to go but I am drawing a blank as far as what the dance gaming at the game arena will entail. Pun not intended.
