Man they didn't even release the Gitmob Spearhead, they aren't getting a Christmas Box.
Skaven and Stormcast aren't go-tos either. There's not pattern of releases to support that idea.
And they don't always do one box per Grand Alliance. They did it last year, but 2023 and 2021 both had two Death Boxes and nothing for Destruction.

So every part of your speculation is faulty
