Still nothing official but everyone would be more than surprised if it wasn't. MMO-Champion is even already announcing it today. With a complete patch list and a list of all their articles about 3.3 (with probably all you could like to know).
For paladins you can find a review of the changes on Blessing of Kings.
Let us all cross our fingers for tomorrow, because no patch tomorrow will probably mean no patch before January.
It's now official. Happy hunting in Icecrown Citadel everyone.
