As far as I know everything they've promised for this one is in the beta and will make it to the final product. Whether or not they can keep their promise of updating the world and story of the war patch by patch remains to be seen.
Blizzard has trouble moving on from that point too apparently, judging by the trailer's focus. Just sayin.
Martial arts fighting anthropomorphic Pandas are a cliche that predates Warcraft and Kung Fu Panda. It's not a thing I'm particularly fond of, but I'm content to tolerate it because I'm enjoying everything else so far. That doesn't make the inevitable and endless torrent of people apparently thinking they're the first to make the connection any less tedious though.
