I think it will do some good on the dev side of things (ie: maybe Notch reconsiders), but for gamers I don't think Abrash has the requisite cachet to overcome their distaste for FB.
That said, when the consumer Rift is released I'm sure they'll fall over themselves to go buy it so it's probably not a serious concern.
