Hmm, I expect something bittersweet.
 * Probably Lucy or Natsu will die. I can see a shocking reveal concerning one of the two that leads to their undoing. My vote goes on Natsu. He either dies, or has been dead all along, or something along those lines. Lucy, in order to keep him alive, signs a contract with him and turns him into a CS or something(her line against Fran could be foreshadowing). OR brings him back using the One Magic which is love.
 * All the gold CS keys disappear.
 * Magic may or may not also disappear, turning the world to one similar to Edolas.
 * Happy and Carla reunite with their families.
 * Jellal/Erza has always been a relationship of tragedy. I can just see one of them dying.
 * Gray and Juvia, I don't really care about them nor do I see them doing anything significant once the story ends, other than being prominent guild members. Right now they are at the same level as Cana, Elfman, Mira e.t.c. as far as it comes to importance. At least for me.
 * Demons vanish. Duh
 * Dragons go back to their era and take the DS with them, maybe.
 * Mavis joins Zeref in an eternal slumber.
 * Laxus becomes Master.

Many of those theories contradict each other but those are things I find possible and/or satisfying. Idk ( ._.)
