I wouldn't count on that either, but as it happens, last year about 3:00 AM Christmas Eve (California time), WT announced the first (and presently only) version of the TextBlade app. Of course, testers have had a number of updates to it, but not the general public.
So, I guess it is possible they may try to do something this year too. I wouldn't count on release. That will happen then they think it is ready, not because of a special date.
There is also the matter that long ago WT said before shipping they would contact people to confirm what keycaps they wanted. Seems to me they'd have to allow days for people to respond in order to maintain the line order.
On the other hand, I believe that was because they didn't expect to have all the different layouts available right away so actually people were being given the chance to order something else if their preference wasn't ready. That may not be the case now. We just don't know. But if they do have enough of each layout, they may not do that email. They may just ship. That would be the only way to make the announcement before Christmas for shipping that I can see.
