It'll come back up in the lame duck session (that's why Harry Reid voted for the filibuster - it's a really weird Senate rule that allows him to bring up the bill again later). I'm guessing after the election, DADT will be repealed before the new Congress is seated because a lot of pressure will be off. In addition, the Pentagon's analysis will be concluded by Dec. 1st and it will probably show that repealing DADT will not have an adverse effect on the armed forces. so that will deny a lot of political cover for people hiding behind the "let the Pentagon finish its analysis first" rhetoric.
I predict it'll pass with the support of at least 3 Republican Senators (most likely Snowe, Collins, and Brown). DADT's going down - it's only a matter of time...
