i would love to see more pets in 1.8 or 1.9 like pet fish that you have to craft a tank for it would be crafted the same way as a chest or furnace just with glass and u would need to catch the fish using a difrent type of rod another idea are falcons these birds can carry a note witch will go to a npc village (npc villages are confirmed in 1.8 click here for confirmation) the note will contain a reqest to the village asking for something like wood steel example (dear npc wood for iron?) or (dear npc can i stay at your village for 3 redstone)
There is a mod called "Mo'Creatures" that does that sort of thing (really nice too~ TONS of tamable animals)
As for the actual minecraft; I'v herd there is going to be breeding since animals will be a 1 time spawning only thing which means they will probably be somewhat tamable (I'm totally voting for spy chicken minions)
another idea is cats,reptiles,snakes ect.
