I think Power Rangers should be enough to keep them going because Hasbro seems to have NO interest in it and will likely be happy to dump it onto PlayMates as long as they're willing to pay for it.Playmates is already having some weird issues, having lost Ninja Turtles for the first time since the original TV series, while ALSO having Hasbro outsource some of their own IP to them. I find the whole thing to be a rather confusing mess, I admit...
But yeah losing TMNT has to hurt, but I also don't blame Paramount on that. PlayMates was by all accounts rather hesitant to break out of what they'd been doing since day one, and Paramount wanted a grander scale for the line...
I can see why some Mattel investors see a Hasbro merger as preferable, but it would be awful for the US toy industry.
Best case scenario is that the FCC forces the combined company to drop some of its IP to avoid running afoul of antitrust laws, and a smaller company picks them up/hires the personnel who will inevitably be let go and we see one of the smaller companies build themselves up, but even then... a HasTell company would be too big to ever truly be rivaled in the Western market, and that's terrible for the industry overall.
