Jak and Daxter: The Lost Frontier was confirmed by High Impact Games on April 1 2009 for release on November 18, 2009. At E3 2009 a trailer was released for the game. Naughty Dog has sold the game development rights to High Impact Games, will this make it better or worse? Initially, Naughty Dog hadn't had any plans for future Jak games, with only hints and comments providing clues to their decision. However, a trademark for a possible Jak and Daxter game was registered at the U.S. Patent and Trademark Office called Jak and Daxter: The Lost Frontier. This was evidence that some sort of Jak game may be in the works. Co-President Evan Wells later stated that the new technology in their Uncharted: Drake's Fortune engine may be used for a new Jak and Daxter trilogy, as well as saying that "there is a lot of interest around the office in going back to that franchise [Jak and Daxter] and seeing what we could do with it using the Uncharted engine." Then, several prototype game cinematics were also leaked onto the Internet featuring old and new game characters in unfamiliar situations (Jak has short-cut hair and, along with Daxter, is interacting with new allies and battling new foes).
