No sooner do I speculate than I find the result in the Guardian:
Best Collection: Mick Imlah - The Lost Leader
Best First Collection: Kathryn Simmonds - Sunday at the Skin Launderette
Best Poem: Don Paterson - Love Poem for Natalie 'Tusja' Beridze
So I guessed one out of three, but the choices all seem fair enough to me.
