Sooner or later, Nintendo or Game Freak will find a way to develop Pokemon that will actually give us more interaction options, and the possible ability to 'hug' them as well.
^ Please Nintendo, make this happen.
I can't remember if I already mentioned this once before, though it would be nice if they could develop a Wii U addition of the Pokemon Stadium series for X Y. and a Wii-U HD version of Poke-Amie while they're at it.
Also, according to Bulbapedia, some of the pokemon not found in X & Y, seem to have a pokedex entry listed in X Y anyway (like Beautifly, or some like Lugia, etc). How are people finding this? I know there's one hacker who posted some new unknown pokemon, but I'm not sure they would find all the text data too. But I donno.
