I wonder if a 3rd Party will tackle a Richard E Grant Loki figure haha, that'd be really unique. Would go with the Halloween costumes from Wandavision, if someone ever makes Wanda's costume. I don't know why Vision only got a 3rd party preorder, would really want them both.
I'm surprised at Knightmare Batman now that you mention it, that was after all the other stuff I read about. I think even Prime 1 had to blur out guns on one of their statues. An expensive statue! Their licensing is out of their minds, but it generally appears to only apply to promotion and that the figures themselves should be able to have them. McFarlane doesn't appear to be including any guns in the new figures though, they've all got swords or something ridiculous.
Mezco stated when their Constantine figure was up for PO that guns and cigarettes weren't shown, but they'll be included in the package and basically explicitly said it was WB/DC not wanting the releases advertised with them. Mafex later put out a thing that they were removing guns from Hush Batman and the DKR Armored Batman figures after they'd already been put up for preorder. I really hope they just include them in the box anyway.
