Defining success for Xbox 360

WinInfo | at | by Mike

So the Xbox 360 is off to a roaring start, with huge lines of people waiting outside of retail stores so they could purchase the few units being offered for sale. But how does one define "success" for Microsoft and Xbox 360? Does it have to beat the PlayStation 3 in the market? Some are suggesting that Xbox 360 needs to outsell its predecessor to be termed successful. I guess that makes sense. The original Xbox has sold over 22 million units worldwide, so that's the goal. That, I guess, and outselling at least the Nintendo Revolution. But here's another bellweather of its (early) success: If Xbox 360 doesn't outsell the PlayStation 2 during the time period before the PlayStation 3 is released, I'm not sure how anyone could call this thing successful.
