Namco is awaiting approval of a new trademark application for "Ace Combat Infinity" in Europe, while it's also opened up a new teaser site, presumably for the same game.
Gematsu spotted the teaser site for a new game from Project Aces, the studio behind the Ace Combat series.
"That day our sky fell, the heavens split to create new skies," says a message on the site.
Ace Combat: Assault Horizon was released for Xbox 360 and PS3 in 2011, so it's probably about time that we saw another game in the series. Whether it'll be for the current generation, the next, or even both, we'll no doubt find out soon.
