How like man? It's still not second place and, seing by their sales trends and incoming games and so on, XBO will have a really hard time even reaching the WiiU, let alone beat it!
I like XBox and would buy it instead of a PS4, but it is very unlikelly that it will be a leading console this generation. My predictions by the end of this year are WiiU 10,5 MM and XBO 8,7 MM, at the most! (let's talk back next January!;)
