Based on the current public info, nothing can be confirmed completely or discounted completely. Currently there are only two pieces that points towards the Sybil attack being used against Tor: 1. Some Tor Hidden Services were uncovered 2. The dates just happen to match dates a research project were running But there is a lot more pointing away from it: the main points are: 1. The FBI already had a source in SR 2.0 2. It is easier to uncover hidden services using endpoint hacks rather than global deanon 3. Given the ability to deanon parts of the Tor network, the feds would have targeted the larger markets and got a lot more arrests. It isn't a coincidence they just happen to take down the sites with the worst software stacks, security architectures and operational techniques.
