I was really hoping they'd just follow up the Enterprise with a Star Trek Advent Calendar. Mirror Spock, Green Wrap Kirk, Rand, Chapel, Fencing Sulu, maybe an Andorian or Charon or Gorn... maybe pink TAS Pompom Tribbles?
Maybe it's a licensing contract thing? Some licenses dictate market (specialty/mass/dollar stores/etc.) while others do specify price points (Funko's Marvel and Star Wars Hikari Vinyl lines had to be $79.99 rather than $49.99 for other licenses, I believe there were similar issues with Diamond's not-quite-Mego Marvel figures a few years ago.) Playmates did re-up with Star Trek again so this might be contractual to prevent them from covering (arguably) the same scales at the same time.
