Thought I'd take a stab at what the two-packs might be, just for fun--based off the 14 figures (not counting the snakes), for a total of seven two-packs. This is assuming all the ones we've seen are from Raiders:
Indy with Idol and Hovito Warrior #1
Indy No Jacket and Cairo Swordsman
Indy in Arab Disguise and Sallah
Indy with Gloves and German Mechanic
Belloq and Ark with Angel of Death
I'm having trouble with where these guys go:
Hovito Warrior #2 -- From the South American sequence, there's two Hovitos, and one Indy--seems like maybe there's one we haven't seen yet. Jungle Safari Belloq, maybe?
Indy with Jacket and Revolver -- This seems to be from the shoot-out at Marion's bar, but there's no corresponding figure. Toht, maybe?
Marion - Given the outfit, I think Monkey Man makes a lot of sense, especially since he's in the main line.
Mummy - This was pictured with Sallah, whereas a Marion in White Dress would make more sense. And if Sallah and the mummy are together, then where does Indy in Arab Disguise go? With Marion, maybe?
