A Netherlands-based Sega fansite recently posted a titillating report
received from an anonymous source, who claimed Sonic Adventure
would soon be running at breakneck speeds onto Xbox Live Arcade. Accompanying this report is the image seen above, which, in addition to listing the game itself, also mentions an "extend package," which ... well, which we can't say out loud without giggling like schoolchildren.
As psyched as we'd be to see the azure rodent make a not-terrible appearance on the 360, we're going to treat this with as much apprehension as we can muster until we hear something official from Sega.
