Appearing in a blue blur on a hedgehog's Facebook page this morning, the first teaser trailer for Sega's next Sonic game features blue blurs both old and new. Is this Sonic Generations?

Signs point to yes. After all, Sega did say they'd be celebrating come April 7, and they have recently registered the website domains SonicGenerations.com and Sonic-Generations.com.

Either way, we've got a Sonic the Hedgehog game coming to Xbox 360 and PlayStation 3 sometime this year, with at least two generations of Sonic packed inside. What does it all mean? I'm sure we'll find out soon enough.
