After that sexy Nintendo Power cover (check it out again after the break) and a pretty legit-sounding scenario, Sonic and the Black Knight is now confirmed as a Wii-exclusive title. Some guy on the official SEGA message boards "confirmed" it was real, but offered no details beyond waiting for the official page on sega.com. So, like the genius detectives we are, a short investigation of the official page turned up this information.
The game takes place in a "storybook world of Arthurian legend," with Sonic wielding a sword to do battle with various ne'er-do-wells in medieval times. Not much else is explained beyond that, but we'll keep you posted on any updates to the official page. Stick around and Sonic will thank you.
