Hope they bring back the Hoenn Battle Frontier. To this day, I`ve beaten the Sinnoh Battle Frontier but still haven`t managed to get all the symbols in Emerald.

^This.

I too have struggled to get all of those symbols too. They were fun and I loved the music playing when you challenged each brain. :D

They teased a facility in X/Y, I hope it meant that one.
