@warcraft is really the only one who announces anything.

But you can be guaranteed if they release information on it.. @WoWInsider and @Boubouille_MMO will retweet it.

You may already realize this, but no Blizzard employees are going to talk about new WoW developments until the content is released (or maybe in beta/PTR ).

Just to spread the word: @Boubouille_MMO is the ONLY Twitter account representing MMO-Champion. Everything else is a copy-cat spambot and has no affiliation with the website.

@BlizzardCSEU_EN (or replace the EN with FR, RU, DE, ES as wanted) Community support.

I follow most of these folk and love keeping up on dev postings too. Sometimes, as much as I love to hear the big news, seeing the little things - their humor, the unrelated quips or digs at each other - brings a real sense of community. This isn't some show they are putting on, these guys truly love the game, their jobs and interacting with us out here.

But to correct Adam slightly:

"...and I'm a tad surprised that so many people feel like it came out of the blue."

But it *did* come out of the blue... forum poster. ;)
