Let's be honest here: I'm way too busy reading all the new information about the upcoming expansion to write about it. So, check out all the goodies over at GameSpy and World of War.net.
One thing I will comment on though: just the other night, my friend and I were talking about just being able to see all the content. (He hasn't even seen all of Karazhan.) We thought: how cool would it be if everyone could somehow see all the raid encounters? Hmm.. it seems that all of the 25-man instances will also be able to be completed with only 10 people. Kind of a normal and heroic setting of raids.
