MP-03 was replaced by MP-11 by Takara / Hasbro. MP-10 replaced MP-01 right after a re-release of MP-01 being the last. MP Rodimus just got a Hot Rod done, though MP-09 already had hot rod... Takara / Hasbro may do more, maybe even Grimlock. Many Fans wanted a v2 Slag from FT, and I think FT is doing right by offering this choice to the members of the Dibot that was done first, at least for those who want it. And I have FT Scoria X and he is my favorite toy I have ever owned and will be keeping it. This new one really good too, and not too big like the GP one to go with my Dino X team, that is if they make an X version. I may just want this one regardless though, but will see once design has been finalized.
