@Trollface, I don't believe anything you say due to your name.
And to other things, this is nothing huge but a MVP just posted this 10 minutes ago on WoW Forums:
Nah it'll be in 2012. It'll be announced at Blizzcon. The World of Warcraft panels reveal that much. Plus, patch 4.3 is sort of the "final" patch of Cataclysm, so we're slowly moving toward the next expansion.
It'll be out late summer or something next year, if they keep a similar schedule as with previous expansions.
To answer your question, however, Mists of pandaria has been confirmed NOT to be an upcoming expansion. whatever this project may be, is uncertain. We may however find out about during blizzcon this weekend. Until then, please do not ask this question again.
This is not true.
I presume you're going by Tom Chilton's comment at Gamescom where he said: "if you look at traditionally how we've handled that race it's been in those secondary products because we haven't realized it in the world. Most of the time when we do anything panda-related it's going to be a comic book or a figurine or something like that."
The keywords here are traditionally and Most of the time. Don't fall for Blizzard's cryptic messages :P
