There will be a total of five LEGO Advent Calendar 2021 sets which include LEGO City, Friends, Star Wars, Harry Potter and Marvel.
LEGO has revealed through a couple of certification pages that some LEGO Creator sets will be getting reissued in different colours.
The LEGO Ideas Sailboat Adventure (40487) instructions were just uploaded to the LEGO instruction database server so now you can build one on your own.
LEGO Marvel The Avengers Advent Calendar (76196) is a pretty good selection to cap off 2021 with seven minifigures and a host of micro builds.
