I, too, have bad expectations.
-The game will be yet another overly-linear one where every town except the one you need to go to for the story is always mysteriously "blocked off" until you beat the next gym/group of enemies.
-Team Flare will be completely and utterly evil, with no redeeming qualities or even any decent ideals. This is a huge pet peeve of mine. Back in the last generation, Team Plasma seemed to be a good idea. They seemed to have noble intentions, but the means of achieving them were wrong. They seemed to be great examples of well-intentioned extremists. This was all actually interesting, until they announced that their purported goal was just a front for WERLD DOMINAYSHUN.
-With the return of Rock Smash, there will be many necessary dungeons requiring 4+ HMs at once.
-Fairy Pokemon will be nothing but Disneyish, pink, sparkly, and girly "KAWAII DESU NE UGUU" abominations that spit in the faces of mythical Faeries.
-Digivolutions Mega Evolutions. Just... Mega Evolutions. I can't look at GF the same way after that unfortunate reveal.
-We will recieve more filler Eevee Evolutions and pointless Digivolutions Mega Evolutions.
-There will be no real rivals. Instead, they'll just be friends. I mean, it's not like Blue and Silver are two of the most popular characters in the games. Oh, wait.
-We'll get 15+ legendaries, with most having some sort of pointless form.
-I gotta use my 3DS. Great. What with the terrible battery life, that means it won't be a portable game. I'm sure looking forward to having to play the game while tethered to an electrical outlet.
