Revoltech Camo Tumbler With Cannon
 

Looks pretty cool. I've grown to loathe TDKR in the last few months though so I won't be picking this one up.

One of those in 3.75" scale would have been cool.

Anybody know what those red circles are pointing out in those photos?

I would say they're pointing out points of articulation for the most part. And 1 of the circles is highlighting a rivet, so makes me think it's actually a firing button or opening point.
