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").
You can watch the first trailer for Sonic the Hedgehog 4: Episode 1 after the break. What do you think?
