WotC has been pretty dreadful about adding novels to its catalog for a while now, and I agree that the release schedule for 2012 seems pretty light. That said, I count five titles scheduled after July, only two of which are Elminster or Drizzt books. But two of the other titles are omnibus reprints, leaving just a single new release that I'm aware of at this point.
