I like how you can bring up your deep rooted hatred of Kamen Rider Build in any discussion.The moral of the story here is that Hasbro seems to have taken up Harmony Gold's mantle of copyright dickishness. Still, I can't support the Kuuga release, it might lead to Kamen Rider Build, the worst tokusatsu ever made, to be unleashed on the unsuspecting public. Can't have that.
The Kuuga Bluray is up for preorder on Amazon, finally, but you may want to hold off for now. It's even more expensive than it is on Shout site.
