Sega has revealed a brand new Sonic the Hedgehog game via Sonic's Facebook page (Dr. Robotnik friend request -- rejected). A short teaser trailer depicts Sonic running through a sparsely colored sequence of checkered hills and loops, before meeting up with an old pal. Classic Sonic is back, pudge and all! Also, we hate to worry you, but it looks like he's been cloning himself.
The game is expected to arrive on Xbox 360 and PlayStation 3 sometime in 2011. We're sure to see more before the blue speed demon's 20th birthday.
