I don't think it's safe to say anything until January and February NPD. January will be somewhat skewed by Xb one's temporary price increase. So Feb will be the month when the playing field is price stable and we'll be able to get a proper picture of non-holiday demand at current pricing.
But based on sales performance last year when PS4 and Xb one were the same price I think it's a long way from safe to say that Xb one is winning America, if by that you mean it will eventually achieve a higher LTD than PS4 and PS4 will never take back the LTD lead. That is still a big maybe.
