He's dead - why would they need anyone to play him?

Because you didn't pay attention enough. There was no announcement but Banno already appeared in Type Tokujo (Part 1 RAW was out for like half of month). He's dead and almost no percent of returning (most likely will get on-screen time through Gou's delusion, though), so why bring up the trouble of annoucing non-special guest that only plays in some minor scene, really? Have they ever announced who is Krim Steinbelt in human form?

Uh...yes? Because we saw his death scene early on as a nightmare he was having. He's played by the same actor who voices him, Chris Peppler.

I mean announce like a post similarly as Medic/Gou/001 Roidmude e.t.c on Toei website or introduced in press conference. I don't recall Krim's actor has appeared in press.

What do you think the new kamen rider is based on the news?

Kill la Rider?

You mean the future one in the Mercedes?

No there was this news that the new rider after Drive is theme is fashion i think.

Remember kids: don't believe JeFusion rumors at all.

Exactly, rumours of this point are quite silly, I mean we have past the halfway point of drive but I imagine it will be a lot longer before we get things.
