Indy with Jacket is the super articulated Indy we saw at SDCC. Indy without the jacket is the action-feature (whipping) Indy we also saw at SDCC.
The German's actually a regular soldier, not an officer. I forget the chap's name that was the officer now off-hand, but he's pretty uniquely uniformed compared to the regular DAK soldiers there. I'm hoping we see him made of course because, well, he was one of the 3 main baddies with Toht and Belloq.
