Sony has put up a teaser trailer for something called EMAGON.
The trailer was accompanied by a post on the Spanish PS Blog. No other blog (EU or US) has published the same post, which probably means someone pushed a button too early.
The video below is entirely in Spanish and shows something of an exploration game. Sony is set to reveal what the hell this is on December 5, to celebrate the 20th anniversary of the PlayStation brand.
This could either be a Game Awards reveal or a PlayStation Experience reveal. In any case, we'll be sure to tell you what it is when we know.
Oh, one last thing, EMAGON is "no game" backwards.
