That's always the dilemma Whitey buy now and get the flights you want by paying more or wait and hope you can get the paltry few seats they offer in Q or L class before everyone else snatches them up.

You can bet there will be cheaper fares, the question is -- is it worth the wait? If you need security for a well-planned trip with advance reservations in hotels etc., I would book now. If $$$ is your only consideration and you have flexibility on dates, you can probably wait.
