[Chasing]

I'd bet that Kenzan, Buster, and Slash will get new upgrades in the form of an adapter; something like the Gashat Gear Dual Beta from Ex-Aid. Maybe a bigass Wonder Ride Book that cycles through 3 stories.
I don't see how else they could really pull it off. There's no way any of them are replacing their Seiken, and I honestly cannot see them releasing 3 separate transformation trinkets, though that isn't entirely out of the question at all. My big question is how the RKF would work, if they go that route.
Either way, I'm really excited for whatever those 3 get, because I know they have to be good. The one hope I have is that they keep the majority of their suits(like Jaoh Dragon did). Kenzan, Slash, and Buster's designs are WAY too incredible to be completely overhauled. Surely, they knew this when they had Calibur upgrade from Jaaku Dragon to Jaoh Dragon. I hope this will be a pattern not just for Saber, but for future suits and designs in general. I really do think it was a genius move by them.
