I want all of them to follow me! Well at least some of my main team like Milotic, Electivire, Gallade, Umbreon or my favorites Absol or Flygon.
I'm thinking that the animations might be like the ones in the Mystery Dungeon games, it would most likely work since those sprites are already made for following someone around. Although if they just rip those animations from those games, that's pretty lazy.:/
I wonder if people you talk to will respond differently depending on the pokémon that's following you. Personally, I think they should. Would be kinda weird if people would be like "Hey, you new in here? You just some random person passing by?" if you had the deity of time walking behind you.
I'm not saying every single little person in the game should have 493 different things to say, but... you get my point.
