Did you buy any of those Articulated Icons? Quality? I'll wait til next year to see if Hasbro makes 6" G.I. Joe for the Snake Eyes movie since those Articulated Icons are likely more expensive than possible legit 6" G.I. Joe.
The white ninja I saw had long sleeves, not short sleeves like original Stormshadow. I thought maybe I could attempt to draw the Cobra logo with a fine tipped Sharpie if I bought it. I thought I saw an alternate parts pack that did have alternate arms with short sleeves.
From seeing the Erik Killmonger military costume & nice assault rifle, Night Thrasher, Winter Soldier, Paladin, I'm guessing Hasbro can easily re-use the tooling for G.I. Joe 6". I listened to a short podcast with Dwight from Hasbro and he says when they decide on investing in expensive new tooling, they like to be able to use it for multiple characters.
