It looks comparable in size to the sleeping killer. Bwana stated that the first few releases will be sans guts and opaque.
I asked him about the size at the NYCC booth and, if I'm not mistaken, he said it should be around the size of the Killer that accompanies Globby.
I'll need new shelves... (These would also make great micros. I don't know how they could do the legs, but... I can totally see an army of them on my desk.)
