A few features have been mentioned for inclusion in the Console Edition. These features are either currently planned for the next update or have simply been dropped or forgotten about.
Note that this page only documents features that were mentioned but are not yet in the game.
4J Studios mentioned they are working with Mojang on combat changes for console editions, but they have nothing to confirm yet.
