Semyon Bychkov confirms to Die Presse that he's returning to Covent Garden to conduct Die Frau ohne Schatten (October 2013), Parsifal (Nov 2013) and Eugene Onegin.
***UPDATE*** Performers are notoriously fallible when it comes to remembering the contents of their own diaries, as Maestro Bychkov's agent has kindly pointed out to me. Sadly, he is not booked for the ROH Parsifal, whatever Die Presse say. But we will still be able to hear him in Die Frau ohne Schatten in March 2014 and Eugene Onegin some time in 2015.
