I looked at the video and I saw NZgamer as one of the users, versing IGN on multiplayer at battlefield 4. If you're having difficulty finding it it shows up around 2:22 when he kills the person on the PS4 section on the video on multiplayer.
So my guess is that NZgamer has been sent a PS4 by sony which is really cool and have already been able to play battlefield 4 on PSN with the PS4.
