If no-one has a backorder on the domain, it should go into the normal drop cycle.
I believe it enters the drop cycle (RGP or Pending Delete Restorable) either a few days after the auction ends, or two weeks after the auction ends. But I'm not sure about that.
Once it enters the drop cycle, it should be around 35 to 38 days until it drops, but my information could be out of date, as it's a while since I studied these things closely.
Maybe someone else can help out with a definitive answer on exactly how many days after the auction closes until a domain drops. (which could depend on the extension, of course).
