So I've been trying to bodysurf over the backlash a bit and think about what advantages the XOne still has, and it seems to me that Twitch integration might be a bigger boon than it seems.
Aside from the hordes of FPS (CoD, Halo, etc.) players, the fighting game community is probably the second biggest group of people innately supporting consoles. For whatever reason, fighters just don't come to PCs, so folks who play fighters have the limited choice of Sony or Microsoft. And aside from all of the fascinating no-scope whatevers, people who play fighters are very public about their accomplishments and want to share their videos, watch videos from other players they like, and watch tournaments that happen all the time.
PS4 has UStream support, but the fighting game community has already established itself on Twitch, so it seems easier for those fans to change consoles and get the ease of direct uploading, rather than change video streaming sites.
Not trying to say either console is better here, but just something to consider about the overall success of the currently maligned XOne.
