Well, Prime 1's version is up for preorder with a late 2021 ETA. $1600 standard, $1900 regular.
The ball is in CoolProps' court. I'm not crazy about Prime 1's base, nor the pose, nor the proportions, so I'm curious to see what CP have done in the [almost] year since we've last heard from them.
Has anyone seen
this video?
Beesub, the artist who worked on it, posted it a while back. I agree that the base is too big, but the design of it is superior to Prime 1's IMO. Feels less cobbled together and the homages to the movie (Casey's head) blend into the environment in a believable way.
