I find it odd that we are getting another trailer about a day before Corocoro. If this is to avoid leaks, then fine, but it makes me a bit doubtful of overlaps. Anyways, the following things have not been covered by Corocoro but seen elsewhere:
-Crabrawler, Morelull, Alolan Raichu, Alolan Rattata, Alolan Raticate, Type: Null, Jangmo-o, Turtonator.
-Ultra Beasts, Aether Foundation, Gladion.
-Signature Z-moves and Munchlax event.
-Poke-Finder
-Version Differences
Add in Rockruff and Cutiefly's evolution, and you have a lot to cover.
