Interesting interview with Toho Kingdom, though it's incredibly redundant to listen to the guy's questions and the product manager's responses.

The Godzilla re-releases will have "some updates" to deco at the very least, 54's gonna have a breath piece.
84 will have "updated back spines, neck, tail, hands"
Ghidorah's price kept going up as they were working on it, so it's scrapped for now. I'd be willing to bet they could go back to it in the future if they wanted.
