I'm looking forward to The Collected Stories of Carol Emshwiller, Vol. 2. Of course, I was looking forward to it in 2012 and 2013, too. (I even pre-ordered before 12/6, stupidly believing it must come out for real this time and arrive before Christmas. Last time I ever pre-order anything. I honor the press for producing Vol.1 and despise it for its atrocious proofreading and schedule-keeping.)
Otherwise, I always look forward to the Dozois annual (#31 this time). And, while it probably wouldn't be a paperback until 2015, I hope Greg Egan has an interesting stand-alone novel or collection after his adventure in trilogy-making. And, while it is a series (are serieses), for military space opera, I look forward to the next paperbacks from Jack Campbell, especially the one from the Lost Stars branch (Perilous Shield).
