If that was the case, Xbox One sales would have picked up after the price drop.
What we see is that they continued the downward trajectory. Therefore the price different doesnt seem to be the main factor.
As for PS3 users not beeing happy and 360 users beeing, well... i strongly disagree. I got a PS4, Wii U a PS3 and a 360. My main gaming console this year has been the PS3 followed by the Wii U.
