But Primal was a considerably simpler transformation. Bipedal animal becoming bipedal robot, Primal is by far the simplest MP to transform. Dinobot is completely different with his transformation and considerably more complex.

Look at it this way, TT would have had to sacrifice robot-mode accuracy if they wanted a more accurate dino-mode and most collectors keep their figures in robot-mode.

Regarding price, he looks to be around MP-8 in height so I wouldn't think $80 is fair. Not to say I want to pay $250+ again but $80 is a bit low considering that's what the old carbot price was and he's considerably bigger than them. Then again I am a stupid man addicted to his plastic crack and probably would fork out $250 for a BW Grimlock.
