If anything Facebook buying Oculus so early is a good thing for people scared of Facebook's impact on VR. I think there is a long and involved period of VR being refined by hardcore gamers before it tentatively ventures into virtual sports and virtual meetups et al. I just don't see the big gaming companies wanting to do deals with Facebook - they hate Steam for its platform control and its communication overlays - they'll be very wary of a Facebook chat overlay finding its way into to Oculus driver v1.2. And I just don't think Oculus as funded by Facebook is going to be living or dieing with gamers feedback like they would as an independent company. I doubt they are going to sacrifice enough to meet those demands and be reshaped by them.
