This month I'm rooting for Science Fiction, because it's the last chance for us to have Science Fiction and Fantasy six months apart. I'm not big on the idea of Science Fiction in December, but the possibility of Fantasy in December and Science Fiction in June sounds good.
If it doesn't win this month then I think we ought to start considering a combo month of Sci-Fi/Fantasy.
It's interesting to look at the options this month and realise that at least nine(!) of them won't become any month's category.
