I think with the help of 2.8, especially once the casuals realize how important it is, and that it is only on PS4, it will drive them to buy a PS4(plenty of other reasons, too) to get ready for KH3, resulting in 5-6 million on PS4. I predict less than a million on Xbox so around 500k. SE has been ignoring it since E3 2014 along with Hashimoto and Nomura last year stating that SE wants to help spread PS4's with their games. That speaks for itself.
