Word buzzing around the internet is that Warner Bros are already looking for writers to work on the Sequel to Zack Snyder's Man of Steel. The rumor is that the heads of Warner Bros are very keen on the upcoming Superman film, so they wanna really push the film and make sure there is a sequel. But they say the same for the Green Lantern Movie which didn't do to good in the box office. Which is also meant to be getting a sequel. So right Warner Bros have a so called "shortlist" of writers. So only time will tell if this rumor is true or not. But i have a feeling it is. As DC might use this movie to build up to their plans for a Justice League movie which hinted to come out 2015.
