Namco Bandai has begun teasing a new Ace Combat game, rumored to be titled "Ace Combat: Infinity." Developer Project Aces is behind this one again, having most recently released Assault Horizon in 2011.
The teaser site (via GameSpot) simply says, "That day our sky fell, the heavens split to create new skies." The Ls in "fell" are notably stylized and larger than the rest of the text. The message also appeared on the official Facebook page.
The rumored name comes from NeoGAF user miladesn, who noticed that Namco had filed a trademark in Europe under the name. With the tease and name getting out, it seems likely that an announcement is imminent.
