So, it looks like there will be a Turtles of Grayskull SDCC exclusive -  it is Skele-Shredder.

It comes with a Bone Throne,  three interchangeable heads -  one is a shredder mask, one is Skeletor inspired and the third is some sort of robotic helmeted thing.    Also, it looks like there may actually be a fourth head as they have a picture of the figure using the head that sits at the top of the throne as well.

I thought for sure, at first I would skip it -  but the variety of displayability is pretty awesome and I love the Bone Throne and that helmet head decoration..   I may have to buy this thing.

It looks like it will be available on Mattel Creations on 7/24 -  there is a countdown clock currently at 28 days, 21 hours.
