Sony America has trademarked a domain name for "helldiversgame.com" as well as filing a trademark for the new "Helldivers." Could this be a new PS4 or PS Vita title?
As explained by Kotaku, the name could relate to the bomber biplanes of the early 1920s or 1940s, although equally it may not relate to either and instead just be a rather interesting name.
Has this got Studio Santa Monica written all over it? Perhaps we'll find out as soon as gamescom.
