I believe the winners and story titles have been known for some time now, but Blizzard hadn't posted the winning entry or the runner-up excerpts... until now. Bashiok posted an update in the official Diablo III forums regarding this.
Not a single Diablo story among the finalists. Not certain about the honorable mentions, but three have the potential of being based in the Diablo universe judging from the titles.
Glancing over this year's and last year's winning entry, it seems the judges enjoy story structure that translates into a lot of "white space". I guess it's time to try and lean towards a more dialog heavy approach.
Edit: The Fan Fiction subforum is probably more appropriate for this thread. Apologies.
