Damn, I envy you! Mine has been stuck in customs since last Friday!
I'm not in the mood to begin assembly yet, so have been looking over the parts to see what differences there are.
On the M4A1 the window on the C-More sight is now red. The grooves in the M4 magazines are no longer painted silver.
The skull is obviously updated and the outfit is weathered.
The Beretta leg holster is also weathered, but the vest one doesn't seem to be. The white stitching on the straps is less prominent, and has been placed closer to the outer edges.
The MOLLE vest holster backplate now seems to be either glued, or much more firmly attached than the original which tended to fall off until I glued them.
The S&W 500 holster now connects to the tactical belt with a shorter, narrower strap with smaller clip. This means it will sit higher on his leg.
The gloved hands are huge improvement over the rubber hands and bulky fabric gloves.
The boots are no longer completely pleather, but have fabric parts with a pair of eyelets on the inner sides.
Disappointingly, VTS still have the Beretta and S&W 500 leg holders on the wrong legs. But that would've meant making more newly designed pieces.
EDIT:
I just pulled his boots off and he has much longer ankle pegs than the original. That explains the extra body height.
Also discovered from going through the spec list that there are six removable rounds in the nickel S&W 500! The chambers are so tiny I had to resort to a finer pair of tweezers to push one of them out to confirm that they were separate parts.
