| They're constantly working on tweaking this or that in the engine already. I don't know of any real changes coming to the UI, (but I bet I could ask around and see if I can find anything out from any of the other Summit attendees, like Dolby perhaps). I do know at least one relatively major revamp which was raised at the Atlanta Summit was a character model revamp is coming.
Now, don't start grabbing torches or pitchforks yet. The biggest concern was whether or not it would alter faces. The answer to that was that the revamp would only be affecting character skeletons and bodies. Some races would alter slightly (I know dwarves were mentioned), but the basic goals of this revamp would be to allow for slightly increased framerates in areas where multiple race models were present (i.e. raids, cities, etc.) and to allow for faster design/testing of new armor models (since you wouldn't have to design it for as many different character model body types).
I'm really, really short on details beyond that, and it wasn't a topic we spent a great deal of time on. I think pretty much everyone agreed this was a "good thing" (TM) and we moved on to other subjects.
