There is a good chance that the next expansion to World of Warcraft will be announced at Blizzcon this week! some of the details of the new expansion have been released, so far none of this has been confirmed but sounds very promising!
That expansion pack is called World of Warcraft: Into the Maelstrom
The Maelstrom area of Azeroth will be opened up for play. Will
consist of various islands and Undermine will have a new neutral city.
The islands will include questing zones, raid dungeons, that city, and a new arena.
The level cap is being raised to 80 with the expansion but there will be no new talents.
Advancement after level 70 will be through Hero Classes rather than
talents. Hero classes will function as subclasses and each existing
class will have 3 of these hero classes to choose from. These hero
classes will not be limited by talent choices. Players will be able to
choose these new subclasses at trainers when ItM goes live.
Currently the Priest and Druid hero classes are complete and the Warrior and Mage are close to completion
Hero classes will be demonstrated at BlizzCon
When contacted, a Blizzard representative responded with, "we
haven't announced any details on a second expansion. We also can't
comment on rumors or speculation."

**UPDATE**
Another quick update! I was searching around a bit more...and it sounds like possibly one of the hero classes for paladins will be called the Death Knight -- No real details except it sounds like it is going to be the section that will officially make Ret Pally's a viable class:) WOOHOO! that means my 64 Ret Pally hasn't been a waste!
