The new Classes introduced in the upcoming Addon Burning Crusade will make it possible for the Bloodelves, the new Horde race, to become Paladin. At the same time the Draenei will be able to become Shamans. Read all about “Stealing the Light” and “Velen’s Vision” here. Personally, I do not like this step at all. But I think its Blizzard’s way to make sure there will be enough characters of the new race available.
Blizzard published more information about the upcoming new professions Jewelcrafting and Socketing. They also included a web based example of how it will work. Jewelcrafters can learn several types of cuts for each kind of gem: the Azure Moonstone, for example, can be cut into a lustrous, stormy, solid, or sparkling Azure Moonstone, and each one of these cuts offers different bonuses when used in a socketable item. Take a look here.
Blizzard is beginning to offer a paid Realm- and an Accounttransfer service for 19.99. Due to high population and other restrictions not all Realms will be available as target from the beginning. Also the account-to-account transfer service is severely restricted. You can read everything here.
Thunderfury, Blessed Blade of the Windseeker will receive a nice change. It will no longer be a mainhand only weapon and you will be able to wield it in offhand. The change has been confirmed on the US Public Test Realm Forum. Personally I do not understand the hype about this change since the sword is rather rare and there is quite a number of guilds out there that have not gotten the necessary drops in 1 year of weekly Molten Core raids.
