Might be. It will be quite far behind YoY shortly because of the Japan launch. However, its baseline in Japan will be comfortably higher throughout the rest of the year, so it will likely still manage to be up overall.
Elsewhere will be close. I have said previously that if it is up this year it won't be by much. As usual, PS4 is talked about like Sony aren't allowed to do anything themselves, and have to sit on the sideline as MS slash prices. Sony will lower the price this year, and when and how much will be the major factor. One thing is for sure, it will still be market leader.
