I think it's possible, but it's also likely that PS3 will win out in the long run. The Blu#Ray Drive is a big deal. If Sony releases a Value Pack later on in the future, say Console and 2 controllers, 1 Game and 2 Movies for I dunno $399 (obviously this would be 2010 - 2011). This will attract buyers who are overlooking it right now. Also when BluRay becomes a bigger part of the Home Movie industry PS3 will boost in sales as well. I think it's reasonable to assume that it will surpass 360 eventually, though it isn't what Id LIKE to see, but will probably be what happens. Already there is a decent sizewd commodity of PS3 selling just for Blu Ray.
