I mean, we have to be getting G1 Skyquake at some point, right? The mold was pretty clearly designed with him in mind, even including the combining-with-smaller-jets gimmick.I feel like if it hasn't happened already, the chances are extremely low at this point.
I would have been interested in a G1 Skyquake, too.
It wouldn't be the first time the obvious use of a mold wasn't ever done, but it would seem especially shocking in this instance.
