I think SE has more surprises up their sleeves, by the looks of it the 2.2 update is going to be bigger than we currently expect. Knowing SE they never show all of their cards before release because they like to surprise us! If you think they rebuilt an MMO in under 2 years just imagine how much they can accomplish for an update.

One thing is certain, they will be introducing a new race which is exciting (i’m betting on Bangaa looking at those ears) from Dorma and assuming Dorma becomes and accessible area of the world they will most certainly be adding new classes one of which I willl be a new tank class because SE would be foolish to add just new DPS classes considering the current imbalance. If they do there will be at least 2 if not 3 new classes.
