Concerning the earlier talk about Battle Frontier facilities, at this point I think I have zero hope for it... Battle Tree seems to be Tower v.4, now with extra nostalgia. Tower is not bad, it's just too plain and we already had enough games with just that.. And it doesn't help that Rotation and Triple battles are shit. Hell, they created Inverse Battles and yet there's no mode for it, they were a lot of fun. Maybe trainers like Cynthia and the Gen I duo can make it more interesting, but it won't change much about it.
It's not that I want a Battle Frontier that much. I think 2-3 more would besatisfying, stuff like Factory, Pike, Arcade and Pyramid. All of them were fun and added an entirely new type of challenge to the game. And hopefully they'll drop Rotation and Triple battles. Also, I'm kind of interested in more facilities that the in-story team can take care of. Like White Treehollow/Black Tower and Chateau. With an awesome prize, preferably.
I hope we'll finally get an interesting post game with a lot of content, it's been too long.
