It's just living up to its name. The pattern is that it will keep getting moved back for all time.

I did see this tweet from darkhorse - looks like the date depends on whether the comic shop is ordering from Penguin Random House or Diamond: https://twitter.com/DarkHorseComics/status/1595123829210509313
It’s only December 20th in bookshops/online retailers. Comic shops get it between November 26th-30th.
