Time will tell but I would be surprised if there is any ackowledement that a division has taken place. That is the concern because CFS I think will always be what they said it was, and XMRV +ve will be a group that whilsts it has been caught up within the CFS cohort is not and never was CFS. Also If 80% is the real figure, it is still not 80% of the total CFS cohort which presumably will still be the much greater percentage. I doubt it will act as a spring board to argue in support of research etc for those that may not have XMRV; neither will it sideline the psychs - if anything things will continue as before. After all it can it not be proven that they gave support to all included within the CFS cohort?
