I hope to see more castles, there hasn't really been many castles introduced in many of the Pokemon games. I hope that N will be in the game, but I also hope to see more castles as well. I hope that there are large castles that you can explore as side quests and as quests after you beat the game. Who knows, maybe the villain team in X and Y will have their main hideout in a castle. Final point, more castles would be cool! I think that the games will be in a more urban type of environment.
