Based on Nintendo's typical release window, this seems completely plausible.
Nintendo's first ever high definition system will be hitting shelves on November 18th if rumors are to be believed. According to Wii U Daily, an internal email from one of Japan's retailers confirms this date. The Japanese date allegedly written in the email is a full week later.
Late November is pretty typical for a Nintendo console release as Venture Beat's Mike Minotti points out. Both the Wii and GameCube were launched on the third Sunday of November, so it seems likely that the Wii U would be as well.
