Joystiq wonders out loud if the shortage rumours going around about the Xbox 360 may not just be a marketing ploy on Microsoft's part. From the article: "The bottom line: in all likelihood, you'll be able to walk into just about any store on November 22nd and obtain an Xbox 360. But all it takes is a little, good, old-fashioned FUD (Fear, Uncertainty and Doubt) to drive sales through the roof and make this rumor a self-fulfilling prophecy." If this is in fact a ploy, it may be backfiring on them. Gamasutra is reporting that an analyst is downgrading his opinion of how the launch will go based on these hardware shortage rumours.
