Sega Delaying PS3/X360 Sonic Unleashed in Japan

Something strange is going on with Sonic Unleashed, better known as Sonic World Adventure in Japan. Instead of coming out on December 18th Sonic Unleashed won't be released on the PlayStation 3 or Xbox 360 in Japan until spring 2009. The official Sonic World Adventure page explains the extra time will be used to further improve the quality of the game. Meanwhile, the Wii version isn't affected and the Night of the Werehog T-shirt in Sega's Winter campaign is still valid.

But, wait a minute Sonic Unleashed is scheduled to ship on every console under the sun, including the PlayStation 3 and Xbox 360, next week in North America.

So, is Sega USA going to announce a last minute delay? Or is Sega Japan getting a retooled version of Sonic Unleashed?
