The numbers all around are poor. But it looks like November usually sucks for Japan with its holiday sales only starting at the very end of November. Only October and February look like worse months overall:

So comments regarding a lack of holiday sales is probably premature. Kid friendly titles like SM3DW, Drum, Pokemon etc. may pick up in the next 5 weeks. That said it doesn't look like SM3DW is really pushing sales so is unlikely to result in anywhere near the bump Nintendo was needing.
