This may be, in fact probably is, total bollocks but...
A poster on the Eurosport forum was claiming that he was involved in the testing and that several top riders are likely to either have results announced against them or at least have the finger of suspicion pointed based on their biological profiles.
He alleges that it is two out of Armstrong, Wiggins and Vande Velde, and also one of the other top 7 riders - so Contador, the Schlecks, Nibali and Kloden.
Claimed he works for either AFLD or UCI and that they are letting info leak out to contradict various public positions, and that it will be confirmed once the dust has settled in 6-8 weeks due partly to political and financial pressure.
Personally I think it is total crap, particularly in regard to Garmin, and judging by his other posts he knows f-all about cycling.
But it is odd nevertheless that there've been no positives this year - from what Bernard Kohl was saying it is still widespread. I suspect the final results have not been set in stone yet.
