People need to quit with the "price went back up" excuses. First of all, that "back up" is only the same price as PS4.
But it being cheaper is a big reason why the system did better in November and December.
Secondly, the price was only up 11 days. The other 2/3 of the month had the price $50 cheaper.
Still doesn't change things for people who still believe the system is $400 and are waiting until later to get a system (whether PS4 or XB1).
Lastly, what's the excuse for February, which has shown PS4 leading X1 on Amazon's Best Sellers list since the first day.
Ehhh... don't think anyone has an "excuse" for February. Seems like many think the PS4 will get this month due to it having a major game.
