As far as I can see, there are pretty much zero bids for even the most attractive generic domains at Snapnames. Admittedly, anyone with any sense is not going to 'bid' there until the last hour, but I suspect that yes, it will be run as a blind auction, because then Snapnames can auction off all the good names they get, regardless of whether one person, two people, or fifty people bid for a name. They could even auction off names that nobody bid for, if they've identified them as worth bidding for. I suppose it depends whether the rubric says that only those who bid before the cut off time can bid in the post-release auction, or whether they just state 'there were multiple bids for this domain, the final auction for this name will end at...' in which case they would be likely to make more money. Anyone's guess.
