I've been told that the follow-up to Jussi Adler-Olsen's Mercy - Disgrace - is being pushed back to June (from March). Proofs should be around in a couple of months. No news on the translator yet. If this happens Disgrace will be eligible for the 2013 International Dagger not the 2012.
The sequel to Lars Kepler's The Hypnotist, The Nightmare (out May 2012), is being translated by Laura A Wideburg. She has previously translated the three Inger Frimansson books available in English and reviewer Maxine, at the time, praised her translations. Laura Wideburg's website also states that she is working on a Helene Tursten novel (presumably 2012's Night Rounds?)
