I'm going to guess that, in this case, we're really looking at PS4 footage.There were PS4 button prompts during last year's Sony E3 demo, which turned out to be a misdirection. Really, unless the game in question is console-exclusive or the version of said game is categorically stated, chances are it's the PC version.
For one thing, the frame-rate is not completely steady. Also, while it's tough to tell from the video, it does not look like native 1080p to me. There are enough issues with the footage that I actually do believe we're looking at the near finished PS4 version.
