I agree, I would love to get this SDCC exclusive. How many times will we see a mini megatron gun in the G.I. Joe line?? Probably never again after this exclusive. I would like to add this to my Joe collection, but I fear the prices will be around what you said.
I would like to see what kind of box this will come in. It would be cool if one side of the box had the Cobra emblem and the other side of the box have the Decepticon emblem.
