It really is an idiotic date. It'll complicate things for Christmas gifts and such, but I feel like they're pushing this to release on physical as forward as possible to keep it in the minds of the Academy.
Czech blu-ray store has it listed for 6th of December and they are usually releasing the same day as the rest of the world so hope it will release at the beginning of December, digital even sooner.
Except for Interstellar, since that opened in November, all of Nolan's home video releases since The Dark Knight have been in early December. I'd say that's a safe bet for when this one will be released as well.
