A little while back, the name “Sonic World Adventure” was found as a strategy guide for an upcoming game. People in the community thought that this meant that Sonic Unleashed was changing its name since this new title fit the storyline. The guys over seas at SEGA Europe responded to this on the Sonic City Blognik, stating that this was the name of the game while it was in early development, much like when Sonic Wildfire became Sonic and the Secret Rings.
But now, Sonic World Adventure has been announced to be the name of Sonic Unleashed in Asia/Japan. The official Sonic World Adventure website has been launched here.
This new website has a very charming layout compared to the generic design of the American/European ones that were recycled from other games’ sites like Sonic Chronicles: The Dark Brotherhood. Not much else has been released for Sonic Unleashed/Sonic World Adventure yet.
