Hard to say. We really need someone living in Japan to comment.
In an ideal work the delay doesn't matter as the other regions seem to have embraced the PS4 so I don't see anything impacting the PS4.
But if you want a conspiracy theory:
Wii U sales have definitely gotten a huge boost, much bigger than just a "holiday" bump. I wonder if it is just marketing and great new games or if the Japanese are pissed off with their Sony for not releasing in their own region and supporting the Gaijins first lol (remember the yakuza game where there is a scene telliing them to go support japanese consoel ps3 lol), so some of them have jumped ship to support the other Japanese company.
