Around where I live, the 3.75 figures go like lightning, while the S6 stuff lingers on the shelves. I don't think they have the inventory to restock the 3 3/4 inch. Hasbro doesn't Care.
"Transformers the live action/CGI Movie" is coming and they need to ramp up those robots that will transform from car to robot and back, yet you still have to add the head and 1/3 of the parts that won't fit when it's in one form or the other! (Do I sound bitter?

)
When is someone gonna make "GI Joe: the Live action Movie" ? Man, could you imagine the marketing drive after that?
