Update to my first page post of what I want/expect:
1) Character customization.
2) Secret Bases (And visit others, unlike Poke Amie's decor)
3) Battle Frontier
4) Move Tutors
5) NO Megas for Kyogre & Groudon
6) Contests
7) Large selection of pokemon (not just keeping them as they appeared before)
8) A lot of end-game.
9) Being able to get all the legends (Jirachi mostly)
10) Breeding mechanics like in X/Y.
11) Challenge mode from the start.
This is pretty much mine.
Also I'd love to get rid of Hms, but if that even happens, it won't until next gen since XY had them.
I hope to see more of the Gym leaders too.
