Is Cataclysm the next World of Warcraft expansion?

Blizzard has trademarked Catayclysm and many are thinking that that's going to be the name or part of the name of the third expansion pack for World of Warcraft. I'm not a WoW player by any means so a lot of what I'm going to say is pretty greek to me but it seems the Cataclysm was a great event taking place 10,000 years ago that reshaped Azeroth. This event happened at the end of the War of the Ancients and the event is also known as the Great Sundering. Those that play WoW is that correct?
