Looks like he comes with a fury form head. I'm still only buying one.

I really like Kamen Rider Decade... the character. So I'm definitely interested in this.

So hold on is there any difference between the regular S.H. Figuarts and the Shinkochu Seiho Figuarts lines?

Yes. As I understand it, SS Figuarts are designed to look more like the proportions of the actor in the suit. See my Kuuga gallery for a comparison of new Kuuga and old Kuuga to see the differences in proportion.
Also, all the benefits of the new engineering they've devised over the last many years.

Sweet thanks for that now I know which ones to hunt down when funds become available...Especially if/when they ever do Kiva or a new Wizard

Yeah, Wizard, W, and OOO are all prime candidates for renewals. Kiva, well, it sure would be nice if Bandai would give us ANY Kiva. :(

It's still absolutely bizarre to me that a one-off form like Kivala would get a figuart before a main rider. It's even more bizarre to me that Saga, despite being in toy purgatory, still at the very least has a prototype where Kiva is forced to suffer not even existing.

Did Kiva really do that badly in Japan or is the form itself just not popular because Emperor stole its thunder?
