Sega has announced that the Xbox 360 and PlayStation 3 versions of Sonic Unleashed in Japan -- where it's known as Sonic World Adventure -- are getting pushed back from their original December 18 release date to the nebulous "spring 2009."
The move doesn't affect the Wii version -- still set for December 18 -- and the only reasons stated for the delay are to "further enhance the content" and "improve the quality" of the title.
The North American Xbox 360 version of Unleashed is set to come out November 24, and Sega's US site for the game has no mention of any delays.
