That's something I hadn't thought of, but that could be some hope for the DCD shipments to be fixed. I can't imagine DC being clueless to this problem existing, and if they know, I could see them putting some pressure on Hot Toys that their shipments better be fine or there'll be hell to pay, and Batman has paid off big for HT, they wouldn't risk hurting their DC relationship and losing the chance to do figures from other Bat films or Batman 3, and any other DC properties.
Here's hoping that could be something, of course, it would still make any replacements that are still riddled with the problem a big FU to collectors getting them. If HT does indeed fully fix it for DC, then every customer should be entitled to get a fixed one.
