Evolt Is Gone, Now What?

Kamen Rider Build has its 44th episode -- this is where the title somewhat says it all, "The End of Evolt". This has me wondering now that Evolt is gone, what's next? He was the main reason behind all the mess but it looks like that there's a much bigger problem now. It turned out that Evolt was double-crossed by Shinobu Katsuragi.

Everything is going on as planned? What in the world is Professor Katsuragi talking about? The scene where Professor Katsuragi creates an escape plan for his son to escape was something. But it turns out that heh as other plans. I think he wants to rule the world with Takumi/Sento by his side -- which could be the reason why he planned for Evolt's downfall in the first plac.e

This also has me interested in one way. If you remember Go-Busters some five years ago -- the Messiah Virus was the Big Bad that eventually got destroyed also in the 44th episode. Evolt is destroyed in the 44th episode too. So what's it going to be now?
