I agree. I do not think Matt was specific as to whether the same sculpt would be used or not. Just, as what was said here, that the Bavarian Army will be revisited.
Considering the improvements since the first release, and irrespective of whether inter Alia the "older" sculpts are being used or not, I would expect to see an even higher level of painting than the first release and a greater number of different sculpts for the same unit.
I may reference the two units of the Westphalians as an example of such development.
I apologize if I caused any misunderstanding. I certainly have no insider knowledge.
