Huw over on Brickset has just posted images of two more LEGO Seasonal Christmas 2013 sets that will be released later this year, Decorating the Tree (40058) and Santa Sleigh (40059). These images are courtesy of Brickset member Gregori and are from the German LEGO store calendar for October. There’s no details on pricing or availability as of this time but my guess is they are polybags that will probably be given out with a certain purchase amount or sold as store exclusives as nice little stocking stuffers during the holidays.
Set 40058 shows a Christmas tree decorated with lights with presents and toys next to it. There are two children minifigures included, one male and one female, and also a ladder for them to climb. Set 40059 shows Santa riding his sleigh full of presents that is being pulled by a reindeer. There is also a older minifigure with short legs holding a police radio.
