"360 lucky to sqeeze by Wii for 2nd"
You do realize that profit and marketshare mean far more to companies then total sales mean to us right?
If total sales mattered then MS could have easily dropped their 2008 prices to remain on top. 360 gained tremendously compared to its predecessor and is in full profit mode.
If X1 makes a profit and only sells 40 million lifetime, that alone is reason enough to make another Xbox successor.
