Russian Sports Minister Pavel Kolobkov told local media the Wada team would return but there was no word on the date and no mention of the issue raised by Wada.
Wada leaders portrayed Russia's willingness to turn over the data as a key reason for agreeing to reinstate Rusada despite its failure to comply with key requirements on the "road map" Wada had set out.
"We've tried to come to terms with the Russians on how this was to be done, and this is the first time since discussing it that they've actually said 'yes'," Wada director general Olivier Niggli said in September in an impassioned defence of the decision. "We hope they'll fulfil that promise."
It was a widely criticised decision and the reaction to the weekend's news was predictable.
"Surprise, surprise - anyone shocked by this?" said Travis Tygart, the chief executive of the US Anti-Doping Agency. "Let's hope Wada leadership has finally learned the lesson and immediately declares them non-compliant. Anything else is simply another shiv in the back of clean athletes."
