TOEI HERO NEXT will come back in February. They have announced that 'they' are going to come back. This 'they' could be Kyoryuger!!
If the leaked pic's Kyoryuger Filming was by Toei then it should have some connection with TOEI HERO NEXT: We are Bounty Hunters since it takes place in the same universe as that of Kyoryuger. Now since the TOEI HERO NEXT had announced this, it would explain why Blue & Gold are not in the scene. In the movie, Blue was the Police & Gold was the Director and the rest were the actors. Probably Gold is planning to adapt a movie about the real events of Invasion by Deboth and Kyoryuger trying to save them.
