If you're a gawker like me in Azeroth's hottest tourist spots, the folks at G4 have these video tours of the new zones for your perusal, hosted not by David Attenborough (although that would be cool) but instead by Blizzard's Alex Afrasiabi, the lead world designer. This is sort of like having a tour of the Labyrinth hosted by Daedalus. The zones in question, Vashj'ir, Uldum, and the redesigned Stormwind, are some of my favorites (although I am bummed out there's no tour of Deepholm, possibly my favorite new zone), and I really enjoyed listening to how Blizzard designed Stormwind from the ground up for Cataclysm. So go check those out.
