It's a simple question: is Microsoft poised to win the console wars?
Winning for Microsoft is really just competing, as their focus is still just to keep another industry giant from becoming the home entertainment PC, the box that hooks to your TV without running Microsoft software (just like it was in the days of Xbox the First). In that sense, Microsoft has secured enough of the market-but more importantly, presence in the market-that they will at minimum cockblock other companies from looking like undisputed entertainment leaders. Well, that's assuming Sony never gets their act together. And they are revving up in a major way and own a lot of their own entertainment properties.
