Even though Naughty Dog has put Nathan Drake aside for the time being, Sony isn't done putting the popular character through his paces yet. Two separate sets of ratings boards have listed "Uncharted: Fight for Fortune" as an upcoming Vita game. This won't be a traditional title like Uncharted: Golden Abyss though. Think less "abyss" and more "golden."
The Brazilian and Australian ratings boards (via Joystiq) both rated the game recently, and the Brazilian board referred to it as a "casino/card game." That board also refers to it as a Vita title, but Australia calls it multi-platform, so we may see it on PlayStation 3 as well.
The developer is listed as mobile studio One Loop Games, whose Web site lists two "secret projects," one of which is its "first big game." The developer previously worked on Sony-branded mobile games like God of War: Betrayal and Ratchet & Clank: Going Mobile. The game hasn't been officially confirmed, but we'll keep an eye out for more information.
