Microsoft IS preparing for life after xbox though. He's absolutely right.
It is a sad fact that the console has had such a...erm..challenging beginning.
It's had exclusives panned and attacked, it's undergone a 180 in strategy TWICE...its creative offerings are simply not putting up the fight that they should be...and on top of which, they've (within a year) gone down to retail promotional sales of 279$ or 329$ if you don't count a free gift card as a sale.
Even worse, it can't outsell its main competition except for during holidays, in one country.
Now MS is saying that all xb1 games are going to pc. They're unveiling a new way to play games (with hololens), they're cutting price again (for real this time). The xbox1 designer even left MS about 3 weeks ago.
I think it's pretty obvious that xb1 is going away... sooner than later. The whole point of the xbox was to recoup the livingroom from sony and reintegrate the computer as a major player. While they didn't necessarily accomplish their goal, technology and social media has undergone a change that has well, put the computer back into the livingroom.
The writing is on the walls, folks.
