This is the GameCube's holiday 2003 (this was also its peak holiday):

November - 754k
December - 1.16 million

Assuming the 69% increase holds for Wii U

November - 334k (198k Nov 13)
December - 774k (460k Dec 13)

I would probably say this year though November might be a bit higher than that and December a little lower than 774k but the overall number (roughly 1 million in Wii U sales from Nov/Dec) is probably right.
