I could see this working like the old BTTF license, where each movie gets a four pack with some bonuses and deluxe figure sets. I could see it like:
Robocop 1 with Robo (grey), Lewis, Bodickker, and either the Old Man or the Melting Man
Robocop 2 with Robo (pearlescent), The Kid, Robocop 2 [with extra Kaine Brain], and Dr Faxx
Robocop 3 with Jet pack Robo, Otomo, The kid, Chief Reed.
Then I'd hope for exclusives of a bloodied Murphy, Battle Damaged Robo, Vandalized Robo, and random thugs.
And finally a deluxe set of ED 209 both in his Robo 1 and Robo 3 incarnations, ala the delorean.
Not that I've thought of this line for a while. If only it would happen.
