Something tells me that the Raimeiken Ikazuchi could have absorbed some of the Ankokuken Kurayami's Powers to become the Gekkou Raimeiken Ikazuchi. And that there will be more V-Cinemas for the other Riders.
I think that Ren Akamichi (aka Kenzan) will be training alone. And that somehow Desast will be involved in this new V-Cinema. Even though his Alter Ride Book and Red Scarf disappeared, I still think that Desast will still reappear in some form. Possibly, 3 Wonder Ride Books will appear somehow. These 3 Wonder Ride Books will be based upon Fenrir (the Wolf from Norse Mythology), A Japanese Tiger Beetle, and The Singing Bone. These are the three parts of Desast's Chimera/Hybrid Megid Form. Now, these 3 will appear seemingly out of nowhere in the abandoned Sword of Logos Southern Base. Ren will be drawn to these 3 Wonder Ride Books, but wouldn't know why. After being drawn to it, he would suddenly have visions of Desast. Obviously shocked, he would grab them and bring them to the Northern Base. With these 3 Wonder Ride Books and talking to Tetsuo Daishinji about his visions, the two of them would put two and two together and figure out that the three Wonder Ride Books contain some of his powers. With these Wonder Ride Books, they will design a new Sword for them.
Anyways, the "Gekkou" Part of the new Seiken means "Moonlight". Just something to think about.
