The Big Cataclysm Info Post

World of Raids.com just posted up a great compendium of all the content they have collected that relates to Cataclysm. The list covers all the major points of Cataclysm, including most of the PvP Changes, such as the new honor system, new battlegrounds, region wide battlegrounds, etc.

If you are looking for a single source to catch up on all the announced changes coming in Cataclysm this is a great place to start.

Also incase you missed it I included a link to WoWTal that has talent calculators for the four classes Blizzard has released a preview for (shaman, priest, rogue, druid).
