Checked both a video review and the gallery on here but didn't see it being used. Maybe I need to check again or look at more reviews.
I think at this point it's safe to say they probably won't/can't bring them over, I just wish we knew why.

It's cause Kamen Rider doesn't have the same widespread popularity as Power Rangers does so they aren't gonna try to distribute every Kamen Rider Figuart even if it's retail. I see why cause there were only two adaptations and only Dragon Knight was good. Also Barricade, http://shishioh.info/SHF_MAMMOTHRANGER.php this has good info on which hands do what for the Mammoth Ranger Figuarts figure.

I'm sure if they weren't going to do Gaim they would have said something by now.

I really don't see any reason why they couldn't considering they have brought everything retail over.

It's probably due to two things: 1. the figuarts got announced for release right near the airing of the first few episodes or 2. cause of the lower popularity Kamen Rider has to Super Sentai cause Sentai has Power Rangers to boost distribution availability whilst Kamen Rider only has Dragon Knight as a decent adaptation & most of the Ryuki riders are exclusives.

If that last part were true though, they would have either cut down on or just flat-out stopped releasing Kamen Rider figures here a long time ago. Plus according to what Bluefin's been saying, only the MMPR-related releases have been selling well out of the Super Sentai-related releases they've been able to work with.

They release the past Kamen Rider figuarts in the past, I see no reason why they can't release Gaim figuarts. They can release Ultra Act Ultraman Ginga and Ultraman is just as niche as Kamen Rider.

Hell my Kamen Rider 1 is a Bluefin release, and nobody knows him in the states unless you're a fan of Kamen Rider outside of Dragon Knight or Masked Rider.

or they know him from the release of kamen rider the first stateside.

Fair point.

I do think Bluefin is going to release Gosei Knight and the Gokaigers as metallic paint sets at the comic con.
