Didn't know about Dory, but the plan is to release Avatar 2 in summer of 2015 and begin shooting next year. There will definitely be a DC film in 2015, if not JL then MoS2, neither of which is something this would want to go up against. If any of those movies come out with two weeks of May 22nd then this is in trouble. Not to mention it might just get lost in the hype of all the other films.
