Grimlock and his fellow dinobots are such iconic characters that I know they would sell. But because of their chrome painting, I think I would probably my several 'spares' as I'd be likely to play and transform the heck out of them. And for those that didn't have Grim and gang, you know you all wanted them. So the nostalgia factor would be a huge sales driver. I think if the costs were THAT expensive to make new molds, then even just Grimlock to test the waters would be successful.

I believe that they must have done this for the G1 prime Can reissue, as there are mold changes from what I've read in reviews, and the original must have long ago crapped out. Maybe we'll see a Walmart release one day?
