Yodhida said they are going to allow player aps or whatever they are called. Add-ons. Just think how awesome it will be if our UI looked like this.

That WoW Interface is so cluttered You almost can't see anything. Though I guess with enough useful add-on you don't have to see anything as all the clutter will tell you everything you need like when I play WoW, I usually have tunnel vision on my Healing Grid watching little bars go up and down and I've set up sounds if i get aggro or am in an AOE so I know to move my character.
