Yep, that's pretty much all that changed between the Lulu book and the new printed book.
But, when the next batch of miniatures are released I'm going to be putting together a new PDF with some other minor rules updates and errata. Basically when building a custom gang, henchmen's attributes can be no higher than 4, professionals 5 but their favored attribute can go to 6. And then gang leaders and hired guns can all go to 6.
Gang Leaders and Hired Guns will be 1 and the same, and will eventually be changed to "heroic characters" .. any gang leader or hired gun can lead a gang, but usually the gang leaders will be a better choice since they will have a skill that benefits everyone.
And for horses, large horses and warhorses will have 2 HP instead of 1.
I was going to wait until I know the new models are actually shipping before I finish the PDF update. I'll probably post it in the next week or so.
