I'd also like to see the 12" line resurrected. They need to make Sallah in Cairo Dig outfit and Ceremonial Belloq to go along with the 12" Ark!
As for 3.75" figs, I think 4 to 5 waves per movie would maybe be sufficient. Definitely start the new line with the wave 5 that was supposed to come out. After that, it would be nice to see figs like:

I guess that is what I'd like to see produced. The collection wouldn't be nowhere near as big as Star Wars but would cover the movies nicely.
