i'll throw in my vote as a former PR person (tho granted i just did PR for rock bands, nothing this big time) - i think it's a positive thing. they are trying to figure out how to cover their asses
... they could be preparing to 'do a Huber' and accuse everyone else of contamination? preparing to bury xmrv for good, that sort of thing.
IF they found some virus in the general population and if then they start faffing about 'no link to CFS, no cause to get concerned, no health risk from the virus established etc... ' - well that would still good news of a sort, 'cos at least we would get the 'official' confirmation that the virus is for real.
the pessimistic voice in me is saying that if they did find some virus in population they would have acted sooner to stop further contamination of blood supplies....
