I can see a animated Kamen Rider film or a OVA series happening. Not a TV series since Bandai don't want to have two toy lines running around the same time. A OVA series would be made for the older fans who don't care for the newer shows.

This. If the mainstream tokusatsu were going to move to animation, then the Kikaider and Ultraman animes wouldn't be one-time things.

For Super Sentai, I think animated movie based on the Goranger manga would be perfect for the 40th anniversary. It won't surprise me if Toei does something Goranger related for the 40th anniversary next year or in 2016.

I can defiantly see Super Sentai being turned into animation, not Kamen Rider yet though.

Amemiya is working on a non-Garo project, which will be released in 2016.
There will be multiple Garo projects for the rest of this year, and next year.

A Kamen Rider anime might be interesting, but I feel like a Super Sentai anime would end up not being that different from shows like GoLion, Dairugger, or other combining super robot shows.

If we're specifically talking about anime adaptations of already existing Sentai series, however, that could be cool in theory, but i'm not sure how it'd work.

Kamen Rider Spirits anime please.

The agreement was said to have nothing other than the comic.

What Garo's anime might mean for other Toku? Nothing, absolutely nothing. For starters, Garo exists in it's own world. The only thing Garo really shares with other toku is writers and actors, most of while already work on anime (especially the writers). Then there's the fact that this isn't the first toku to be turned into an anime. There's Kikaider the Animation (and a movie featuring Inazuman), there's SD Riders, and there's Den-O's Imagin Anime. These anime's existence have changed nothing about toku. Garo isn't going to change a thing either.

Regardless, I'd be all for OVAs of Kamen Rider Spirits or Jetman's sequel. Stuff that feature characters that would either be hard to get back or need recasting due to age.

Although I still stand by my original post, reading this thread and thinking on the concept, has made me warm a little more to the idea.

For Rider, being animation, they could really go nuts with the Rider forms. Characters like Os especially could have had some really insane powers if given the freedom animation provides, especially if they imbued the forms with the more monstrous aspects of the SICs.

Sentai too - especially with the robots. Stacking in the real world with those cheap cardboard suits and model buildings looks downright pathetic and awful but in animation you could genuinely find ways of stacking trains on top of dragons on top of giant buildings that are actually tanks in a way that works, is cohesive and can still move. It might even be cool.
