Glad to see this thread back up and running.
I'll play the guessing game too with "The Terminator" series using NECA's formula from their T2 line with several different versions of the T-800 in the first 2 series and the 3rd series introducing a new character.
Series 1:
T-800 (TechN Noir version with Uzi)
T-800 (arm & eye surgery scene)
T-800 (possibily another endoskeleton re-release)
T-800 (12 inch version of the Tech Noir figure)
Series 2:
T-800 (Police station assault with Gargoyles, shotgun, and assault rifle)
T-800 (Battle-damaged version, after the Terminator is run over by the truck)
T-800 (12 inch version of the police station assault figure)
Series 3:
Kyle Reese (Trenchcoat and sawed-off shotgun)
Kyle Reese (No trenchcoat and duffle bag with explosive charges)
