The final battle better have Geats, Tycoon, Na-Go, Buffa, PunkJack, Hakubi, Ziin & Kyuun together against the final boss!

This was uploaded to the Geats production blog, Seems like Tycoon shogun will appear in episodes 41/42. I'm guessing Buffa Maou will debut immediately after.

I believe so. Personal wish is we finally get Ben and John fight scenes as riders later on as a surprise. That said I can't complain with what we have so far.

Is there any chance for Na-Go to get her upgrade through a Girls Remix sequel with Hakubi at her side? Plus Hakubi definitely needs to come back and get her own signature Raise Buckle.

We might just get that, but at the moment, we should be focusing on the implications of Ace having taken full control of the DGP.

wondering if this could lead to a confrontation like in Gaim?

A final three-way battle between Geats, Tycoon and Buffa who all obtain the power to remake the world via their final forms. with Kekera and Beroba sticking around, they probably may help their riders get the final forms.

What if possible Kousei Kurama becomes “Dark Geats”?

New rumor guys, apparently there will be a new Rider called Kamen Rider Izanagi who will use a black version of the Boost MK IX buckle. His buckle will include a 2 new ID cores, the Izanagi ID core, and a rainbow Geats ID core.

It's unknown if Izanagi is the final boss or the movie villain.

My guess is that Izanagi will remain movie-exclusive, but that's mainly because Seeker hasn't returned yet.

And how befitting cause apparently Izanagi in mythology has to do with creation. Aligns with Geats I think.
