As for the Raiders lineup, besides the 7 shown, they need to at the very least get us Indy in German outfit, Toht, regular duds Belloq, German Mechanic (bald dude) and the German Commander (dont know his name... the third guy standing at the ceremony altar when the Ark is opened, who then melts!)
I think the 5 you mentioned from the Temple of Doom are guarantees! However, I was thinking Short Round and Willie would be packed together. Also, maybe a standard thugee guard as well. That would about wrap up TOD, except if they were really nice and gave us the tux indy with nuerhache urn and Lao che with diamond!
As for Last Crusade, I think we can count on Henry Sr. I believe he was mentioned in one of the past hasbro Q&A's with other figures and they said all figures mentioned including Henry Sr were strong candidates and would likely be included. I would guess LC containing:
Young Indy with cross
Donovan with false grail
German General (not sure what his name is, the one indy fought on the tank)
Generic German soldier
Hopefully they will give us Brody, Elsa, Indy with tie and Casim before the line ends! So that is a total of 29 figures covering the three classic films. So add that to an estimated 15 figures for the new movie (max!) and that would bring the total line count to 44...
I dont think that is much considering we are getting 30 alone in 2008. I would be ok with the line ending as long as we got the characters mentioned above.
BRING ON THE INDY LINE!!!!!
