For those of you who are interested, WoW Insider's Olivia Grace covered the Temple of Kotmogu and Silvershard Mines earlier this month. Her previews don't have as many pretty pictures, but they're more in-depth on gameplay and tactical information.
In addition to the battleground previews, the official site was updated with a Mists of Pandaria Bestiary. The bestiary will give you a first look into all the new, non-playable races you'll find on the Wandering Isle. You should totally check out the Grummles -- they're my favorite new race.
