Playmate's is finally on their way out and Mattel is taking their place. Not much in the way of details, but figured this was still worth creating a topic for... for however long the forums are back up anyways, lol...

Mattel Acquires The Teenage Mutant Ninja Turtles Toy License - The Toyark - News

They're apparently already working on a toy line for the Mutant Mayhem sequel, and apparently even a line for a CGI/live-action hybrid movie that's coming in 2028 (first I heard of this was this Mattel news). Their stuff starts sometime next year, so it'll probably be a good while before we see any of it, but I'm somewhere between excited and hopeful. Mattel usually does a pretty good job with the kid oriented stuff, so that will all be solid. That said, I hope they also at least attempt a collector focused line as well. If nothing else, some figures based on the crossover comics with DC would be nice now that they'll be doing toys for both properties.
