Hopefully Pandora/Avatarland will be done and open. Last I heard the unofficial word is they're pretty much on schedule for a 2017 opening. Hopefully also they'll have the nighttime shows figured out at AK by then.
I would not expect DHS to change much between now and then from a "what's open" point of view. I don't think Star Wars will be ready until 2018 at the earliest and likely the same for Pixar. Construction should certainly be well under way, but other than peeking thru walls I wouldn't expect much.
I would think Disney Springs should be pretty much in its final form a year from now...it's getting close rapidly.
