Sonic the Hedgehog in Smash Brothers Brawl?

Not sure if Best Buy actually knows anything at all about a certain game they will be selling in the next few months, Super Smash Bros Brawl, but they appear to think that Sonic the Hedgehog will be making an appearance in the game. At this point he still seems like a very likely choice for a second third-party character to join the ranks (alongside Snake from Metal Gear Solid) but nothing has been confirmed. If you're a Sonic lover, looking at this promotional material from Best Buy, there could be a chance your dreams come true. Or maybe the guy who made this has no clue about gaming and thinks Sonic is a Nintendo character so he thought he'd put him on there. Who knows?
