The Gokaiger change into Dekaranger, Hurricanger and various Reds:
The first ending had Goranger to Liveman, this one has Turboranger to Timeranger, I am guessing the next will have Gaoranger to Goseiger and they will rotate 3 endings, one per episode, or change them constantly like Go-Onger.
Small pics from Toei.co.jp:
Looks like Gokai Blue will become Big One and AbareBlack and the girls will become Gao White, White Swan, Ninja Black and Go-On Black. Wow, another black with skirt. Maybe we will get Green with skirt!
