All .com domains go into Pending Delete 75 days after they expire, and drop on the 6th day after that, irrespective of the registrar.
Additionally for Fabulous they partner with either Snapnames or NameJet (I can't remember which one), and are put up for auction around day 35 (but check them out from day 35-45) in a Pre-Release Auction. If someone bids on the domain, the age of the domain is retained. If more than 1 persons bids, then a 3 day private auction between the bidders ensues.
The advantages of buying in this Pre-Release auction are 1) The age is retained, 2) you are not having to compete with all the drop catching sharks that circle around if a domain actually drops.
