it all made some sense, until the conclusion, no way the XB1 will sell 10 million by years end, it still has not doubled the 3 million sales it did on launch!
And for third party titles, the problem is that despite them being on the xb1, their best console version is on the PS4 (in some cases they're equal or barely different, in other cases the xb1 version has lower resolution/frame rate or is broken in some other way)... no matter what you think of the gap, it's there and people will buy the better console to run the games they want, everything else is scemantics.
As for the exclusives, I would say that Nintendo's exclusives are able to deliver real console sales bump, something that MS's titles have proven unable to do so far.
So, I think the xb1 will continue to sell more on most weeks (globally) but I would argue that it will not catch up to the Wii U weekly sales wise, not until mid 2015 at best, if it ever does, Nintendo are some sneaky bastards (MS are way too serious and businessy, as opposed to playful, into their approach to "fun"... Nintendo will come up with truly surprising games like splatoon, or they'll associate themselves to them).
As for total sales, it may just never happen.
