Legion Developer Update
This afternoon there was a Legion Developer Update livestream on the warcraft Twitch channel. Those who missed it, who would like to see it, can view it here:

There's also a breakdown of the various items discussed, including the levelling process, dungeons, artifacts and legacy/pristine servers on Wowhead.

I've had confirmation that, as usual, although emails for beta invites will be coming out, they are generally just a "notification" .. you don't need to click on any links on them in order to activate a beta invite.
If you do get an email, the recommended path is to go to your battlenet account direct, NOT click on any links in emails.
I've also been told that often accounts are flagged for beta before emails are received - so if you're really desperate (and/or hopeful) then you could just keep checking your account.
Watch out for scam emails!
