I find this interesting. With that small sample size, the end results may be off by quite a bit, but I do think it shows a shift in mind-share in the US. With the PS4, Sony is at least starting off on even ground with the Xbox One. I'm still calling the US with an eventual 55/45 split in the PS4's favor. That's pretty amazing, given how much more popular the 360 was than the PS3.
Sony has done themselves a lot of good recently, starting with PS+ and making improvements across the board, but Microsoft's missteps have been just as big a factor.
What's really interesting is that, not long ago, many people were predicting the PS4 to finish last and that Sony would be pushed out of the home console industry.
