Sega has officially lifted the lid on Sonic the Hedgehog 4: Episode 1 - formerly known as Project Needlemouse, which as promised takes the blue sprinter back to his roots in a 2D platformer.
Headed for PS3, 360 and Wii as a downloadable title, Sega's describes the game as the "first part in a much larger adventure".
The game takes the original 2D platform mechanics of classic Sonic and refreshes it all with shiny 3D. No mention of a release other than 2010.
Here's the first teaser trailer (via GameSpot):
