Here's a poster for the Sonic vs The Black Knight game for the Wii. It's pretty dramatic, with Sonic wearing the gauntlet & wielding the Excalibur sword from the game as the titular Black Knight is rising out of the other half of the poster with his lance. Above Sonic, you can see Knuckles & Shadow dressed in their armor to add mystery (What will their parts be?) To the right, you can see everybody else like Blacksmith Tails & dress Amy. There's a picture of the box, the logo, 4 screen shots with descriptions & the release date. It likely talks about how the wiimote is a cool way to control the sword.
