While it’s always been known that “Project Needlemouse,” announced by Sega last September, was the codename for a new 2D, console Sonic the Hedgehog title. It was subsequently revealed (much to our delight) that Sonic would be its only playable character, and we now know that the game will, in fact, be a direct sequel to 1994’s Sonic & Knuckles on Sega Genesis. Not only that — it’ll be (wait for it) episodic.
We also know that the officially titled Sonic the Hedgehog 4: Episode 1 looks like a proper Sonic game — i.e. there’s hope for it yet.
GameSpot, which has a first look at the blue bolt’s new downloadable XBLA, PSN and WiiWare adventure, reports that “episode 1” will be available on all three platforms “this summer.” Additionally, Sega confirmed to the site that the game will support online leaderboards and motion control on Wii and PS3 (SIXAXIS for the latter, sorry “Arc”).

Sega’s just revealed Sonic the Hedgehog 4 for PS3, 360 and Wii.
This was the title previously known as Project Needlemouse.
It’ll be digitally released in episodes, with the first part due this summer, and is the first true sequel in the series in over 15 years.
It’s a 2D game with 3D graphics.
Despite it being Sonic and what’s happened with the series recently, it’s official: we. are. pumped.
Get the first trailer below, thanks to GameSpot.

We have found an image within the Sonic 4 website. The “mystery console” that’s locked out at the bottom of the game’s website will be the iPhone. “Episode 1,” which had a vague “summer 2010? release, will be out in July.
