Dinosaur transformers appear to be popular in Japan, at least to me. After all, almost the entire Predacon force of Beast Wars Neo was made up of dinosaurs! But then it occured to me that almost all of the Dinosaurs released in Japan post Dinobots were all Decepticon/Predacon in origin, with the exception of BW Dinobot(who techincally was a Pred). Heck, the original Dinobots in Diaclone, from my understanding, were bad guys to begin with. And in one of the Brave series anime's the enemies in the show(no figure releases or Grimlock) were slightly remodeled Dinobots.
All the other Autobot/Maximal dinosaurs released were done by Hasbro as either repaints(Armada Dinobots, BM Dinobots, G2 Dinobots), or as original figures(Pretender/Actionmaster/Energon/Classics) Grimlock, Swoop, and the Mini-con Dinobots.
So, were the Dinobots possibly shelf-warmers in Japan, and they don't like good-guy dinosaurs? BT Grimlock does not count, cause he wasn't a Dino, and any PVC's or whatnot don't either, cause they don't transform. Maybe that's why Takara didn't do a Dinobot reissue.
