Probably it will sell even more than that now, because the price was slashed to 450 dollars with a free game, which puts it at the same price that the PS4, and with a free camera.
That will ensure a healthy 2014 for the ONE, now, it just need the games, and they are coming as well I think.
That said, I have both PS4 and XBOX ONE and the PS4 is much more appealing and estable, althought I enjoy both consoles, but I think that the PS4 will stay ahead because of free PSN PLUS games, better indie support and the amazing Sony exclusives.
