Not a big fan of Nürnberg Christmasmarket as there are mostly 3 different and more or less identical types of stalls: Sausages, Erzgebirgs-sttuff and sweets. This year it seams at most markets that 80 % of the offers are identical. If you visit Munich and have easy access to the Nürnberg market do it as well. Otherwise skip it, it´s not worth a journey.

P.S. I guess you already traveled, right?
