There is several scenarios still left though. Like they have yet to do Weather based balls or Season based. There are no Day time enhanced balls. They could also make pokeballs based upon areas like caves, marshes, tall grass. There is still plenty of options I just hope they don't go with the same generic stuff like they have been with Quick, Timer, Dusk, Repeat, Nest, Net, Heal. If they go back to what they did in Gen II then I think they would do great but keep a few of the useful ones.
