It is kind of interesting that people are latching on to sci-fantasy as a subgenre. It isn't my usual cup of tea, but I have been enjoying the stories on pod castle this month. Maybe I am a closet sci-fantasy fan.
I am more interested to see if there is any "weird west," "historical fiction," or "prehistoric fantasy" in the contest. Of course I am a New Mexico boy with a background in archaeology, so perhaps it is not surprising that I would gravitate towards those subgenres.
I think we will see a ton of urban fantasy, steampunk (which I consider sci fi), and fairy tales, as those appear to be what is big in fantasy literature at the moment. Of course, someone has to do a traditional sword and sorcery. If someone puts out a story which contains an elf with a bow and a dwarf with an axe, I will vote for it just for the novelty of the concept! You are probably not going to win, but you have cojones.
Also I am curious about grimdark. I have recently become fascinated with it as a subgenre. Fantasy that pushes the boundaries of taste is awful and yet oddly appealing. It is to fantasy what splatter punk is to horror... and while I hate to admit it, I love a good gore piece every now and then.
