Pops is a great figure I own him and love mine but I can see why no one would want him since the film was not well received. I dig pops and it is sad this may be the only endo we are getting at this scale but I will get it. I haven't ordered yet I'll wait until it starts shipping and I got some reward points to get rid of so I will use them on my order. Hopefully at some point we get another Terminator or Predator 1 or Dutch or Rambo and Rocky figures. I'll be happy and keeping my orders for all. I just don't think we will which is sad.
Your right the Pop's figure is very well done for sure, one of the best likenesses of Arnold to date it just not the most interesting figure, it just looks like old man Arnie heading out for a casual night out to me, the movie didn't do it for me ether. The big problem with the Terminator franchise is holding on to Arnold as Terminator instead of passing the torch or just moving on to the future war as the movie's direction was meant to head sort of like Salvation.
At this point I don't expect to see anymore Terminator stuff from Hot Toys except maybe the T-2 Endo if were lucky, Dutch 2.0 could happen but I don't expect to see it anytime soon and same goes for Rambo. As for Rocky they could have jumped on the hype around the last Rocky movie which would have been smart but that ship has sailed, not that its not iconic just not a hot topic.
The Alien line could see a spike of interest come back to the main streamers with the new movie coming May 2017 so if they were smart they would put some PO's up in time to correspond with the Trailers that should be coming in the next few months.
