Bart Sher filming Oslo?

I read a when back that Bartlett Sher was making his feature film debut with an adaptation of play Oslo- which I missed here in NY- and in London- but two weeks- and it is one of the plays I really regret not seeing. Being from Atlanta- I make it to the city as often as I can- but my timing was off for Oslo. Anyone have any information about Sher directing the film? I read he was going to do it- but he seems really busy- a film would take a major chunk of time- maybe after MFL dies down? Any chatter about this film?
