I think that for sculpting, detail, and the possibility of a Star Wars scale Indy line, Hasbro would be great. However- they ARE pretty much a kid's company. Thus, we would probably not be seeing armbands with swastikas on them, and a figure of Hitler, cool as his cameo is i TLC, would be totally out of the question. If a company like McFarlene or someone else who could have articulation as well as great detail, but is more of a "grown up" company, we would see some of these things. I remember seeing ads in ToyFare for some 12" military figures with some famous German General and the WWII Afrika Corps or something, and these bad boys are definatley aimed at collectors.
On the subject of a whipping, spring loaded arm...no. Stupid idea. Maybe good for an Indy Happy Meal figure, but not for something that collectors are going to buy. Voice chips could be cool, but after everybody's reaction to to the EPISODE 1 COMMTech chips I think that the majority vote says no- especially after they raised the price from 5.99 to 7.99
