Man of Steel 2 will happen at some point
A full on sequel for Man of Steel had been in the planning stages until Warner Bros decided to fast track their universe building but the good news for fans of the flying one is that it will happen... eventually.
Superman is still a priority for Warner Bros and you can expect him to get his own solo sequel at some point- in case you haven't realised that definitely means he isn't dead. Because he's Superman obviously and that mound of earth totally moved at the end of Dawn of Justice.
