Seems like it's a pretty limited run, and I think that has to do with the license crossover fees. I only know of the four figures, and have heard nothing of it extending. I think the two properties are too disparate, and felt the same about TMNTxMotU. Not everything works, not everything needs to cross over. So they're not my thing. I might have caved if it was Transformers turning into MotU vehicles or something.I didn't even know this was a thing, let alone that old.
