Phil Spencer was assigned the role after major executive-level shakeups as well as several key XBox team members saying bye-bye to Microsoft. It's not like he was put in the role at the beginning. As such, I find it hard to give Microsoft the benefit of the doubt, as if they finally realize "Phil is the right man for the job to get us back on track". If they really believed he was the right man for the job, why not assign him this role years ago?
No, Microsoft believed whole-heartedly in the idea of the Xbox One and Phil's new role is simply to reassure gamers that Microsoft "is listening to their fans" (seriously, he says this in every single interview) and they're totally dedicated to gaming. I think perhaps they realize that the whole TV TV SPORTS focus isn't going to skyrocket right out of the gate like they previously hoped. Cart before horse. Now they're scrambling to establish the installed base with gamers so that they can later return to their original plan (not necessarily the DRM, but definitely the TV and integrated social media stuff).
Thing is, the execs said that same exact stuff about being dedicated to gaming last year, too around the time of the Xbox One reveal. It's not a new line. I suppose it's more true this time around because Spencer is saying it, right?
