The Buzz: Sony has registered the name "Jak and Daxter: The Lost Frontier" at the U.S. Patent Office.

IGN reports that Jak and Daxter: The Lost Frontier could be the title of the first PlayStation 3 instalment of the Jack and Daxter series. The US video games site discovered that on April 21 Sony registered the name with the U.S. Patent Office, with notes that the game will be an all-new "real-time online networked game."

What system the game will appear on is unknown, but series developer Naughty Dog has been hiring for a dual PS2/PS3 project that is yet to be revealed. As with pretty much all the news this week, expect more information next week during the E3 madness.
