Hey, I haven´t been around for a week and am only now catching up with the new leaks and datamining... I have a few questions that I hope someone can answer...

1. Is the datamine complete, or could new things still be discovered?
2. Do we know all the Trainers in the Battle Tree already? Which ones are there?
3. Will we be able to rematch all the Kahunas, Island Captains, etc in the postgame? Not being able to rematch gym leaders in ORAS was disappointing imo
4. Can we build our gym in the postgame? What are those empty squares for?
5. Do we know what Islands can we build in Poke Pelago? Are they customizable like Secret Bases?
6. Does Festival Plaza have single player missions like the Funfest Missions in BW2? Like searching for berries, or battleing Ace Trainers, etc. Or are they only multiplayer missions in SM?
5. Can the Battle Royal be challenged ingame together with 3 AI rivals? Or do we depend on other real life people to play it?
6. How many returning characters do we know of?

There is just too much information to catch up with, so some help would be great ;)
