That's strange...
A couple of months ago I got a (really cool) tour of the animatronic costume shop (located inside the MK costuming building behind the park). We got to see repairs of animatronic costumes and skins they were working on as well as flip through original WDI reference binders of each and every animatronic at WDW. Quite cool.
Anyways, we also got to see an entire stack of renderings for new costumes for the SE update. They were the originals from the Costume Designer, whom I was told currently designs for movies (I can't remember her name). The costume shop manager (who was giving the class/tour) told us that she - as well as the entire production team - are going for a much more 'dramatic, hollywood-style look and feel to each scene, much more dramatic lighting and scenic work, as well as hollywood-epic style costumes'. She then showed us some really interesting renderings for the Egyptian monarchs as well as players in the Renaissance scene and the newsboy.
The thing is...the newsboy looked very similar to how he looks now. She told us they were going to 'beef up' his movement, but mentioned nothing about the Civil War...hmmm!!!
Just thought I'd throw in my two cents...from the inside! ;-)
