I just saw a story on Yakface that apparently there are some new Indiana Jones figures on display at SDCC. Here's a link to the photobucket gallery: http://s560.photobucket.com/albums/ss44/jcazale/
The thing is, if you look at the close-up of the accessories that come with the Toht in the Toht/Dietrich 2-pack, you'll see on the next level down there looks to be a guy with his arm "on fire" - based on what I can see of the outfit it looks like he's from the scene in Marion's bar at the beginning of the movie.
If these are indeed coming, I am not surprised at all that they're using the fact that they have two Toht head sculpts to anchor two of the two-packs.
I'm not 100% convinced that those rumors of the Ark Ghost were indeed legit, since I highly doubt that ANY of these products have been worked on "new" since the line went on "hiatus".
My guess is that there are more of these since there isn't a single Indy figure pictured and with the exception of Toht, none of the lost RoTLA figures figures are shown (Indy in German Uniform, Saphito, Marion in White Dress, German Mechanic)
