Speaking to Official Nintendo Magazine (full interview to appear in the next issue which hits stores on Friday), Sonic Team's Yoshihisa Hashimoto has revealed that gamers should expect Unleashed to feel more like a third game in the Sonic Adventure series than a follow-up to either the previous Xbox 360 and PS3 Sonic title or Sonic and the Secret Rings.

"As a development team, we originally started off this project planning to create Sonic Adventure 3", Hashimoto told the magazine. "In our minds, this game will have more in common with the older Sonic Adventure series. It has no relation to Sonic the Hedgehog or Sonic and the Secret Rings".

Sonic Unleashed is in development for Xbox 360, PS3, Wii and PS2.
