-The new Mewtwo seems to be a retcon of the old Mewtwo, as there is absolutely no reference to the first movie.
-The new Mewtwo form seems to be triggered at will (in the anime canon) but can only be sustained for limited periods of time. During this form, Mewtwo can slow down time, and therefore move extremely fast.
-The Genesect that befriends Ash isn't necessarily a girl; Rather, it's got the personality of a child, as noted by the frequent utterance of "I want to go home..."
-The red Genesect is a real jerk. <_<
-In the Pikachu short before the movie, Sylveon didn't do anything that would have implied it was a brand new type, so it's a good thing GameFreak told us at E3.
-While Sableye was present in the movie, it did NOT evolve.
-The new Treant Pokemon was shown in a short gameplay clip before the movie. Tiny chance of it being related to Sudowoodo, but I'm unsure.
That's about it. Thoughts?
