It was for April Fools. The "game-play footage" looks like its from the new mobile single-player game recently released (or soon to be released, I can't remember) in Japan. Also I would say that is even equates indirectly to viral marketing for Wizardry Online. Now why Aeria would have an April Fools joke that risks introducing players to a Sony game is beyond me and is likely an oversight in a badly planned April Fools joke.
This is all conjecture though and I hope as much as the next gamer that this is a real thing.
