I received both the January 2011 LEGO Catalog and Club Magazine in the mail. Both are heavily focused on Ninjago. The cover to the catalog gives a good view of many of the minifigures that come with the line, like the four-armed Samukai. It would appear that the upper torso sits on a regular fig torso and the jaw is hinged. Other fun details like the DX versions of the ninjas, the fact that skellie Chopov comes with a black pot helmet, and Krazi has a jesters cap. Hopefully your catalog is in the mail now so you can check them out.
There was a fun little 'Easter Egg' on the back of the LEGO Club Magazine. The wall the crook is trying to jump features graffiti tags from several artists including Shepard Fairey, Kaws, Banksy, and Futura 2000. Looks like someone at TLG is a fan of contemporary art!
