I get it, I've only read the headline but my take on it is:
Nintendo wins because last generation they were slaughtered by Sony and even Microsoft sold more consoles than them.
Microsoft do ok because they have clearly taken sales from Sony but probably haven't done as well as they had hoped
Sony lose because they had such a huge lead and advantage last generation but blew it.
And welcome btw...just don't be put off by the avalanche of put downs that you are about to get! :P
