Materials related to the unannounced fifth main game in the Splinter Cell series were also included among the files. The game's logo reveals that the game is entitled Splinter Cell Conviction.
Unsurprisingly, Ubisoft also looks to be adding another game to the Prince of Persia franchise. The leak included concept artwork and a logo for the game, but as of now it appears to have a working title of simply "Prince of Persia." The three previous current-gen Prince of Persia games were collectively referred to as the Sands of Time Trilogy, so it is likely that this new game is starting its own progression of games.
Other unnanounced titles include Surf's Up, a surfing game featuring playable penguins, and a PSP game based on the Rocky films that appears to be entitled "Rocky Balboa: It's not over, until it's over."
