55M is a very good number for MS, that's about 9 million consoles sold per year. Add to that the huge number of LIVE members I think they've done great. I think the most important aspect of all of this is the user experience which Xbox360 and MS provided so well. Console sales is only one part of the overall user experience. The release of the new smaller Xbox and Kinect was a very good move. The new Dashboard is nice too. MS did everything right this generation.
