This is awesome! Of course, I'd prefer MM x WaT or Divas x WaT. All together looks so big and I prefer it when groups are smaller lol Anyway, it's still great. It will it be the first time for MM to collaborate with outsiders (non-H!P people), right?
There's a curious situation now: While Fuji TV relied on GYM (Yama-P and a Thai duo) to sing the championship theme, TBS relied on WaTxH!P. On one hand, GYM's weight is mostly Yama-P (the Thai boys are not much known) attracting to teen girls. On the other hand, WaT and H!P have two very different and hugely big fanbases, gathering boys and girls of all ages. It looks like that the battle will be also out of the play-field.
