LEGION announced as the next WOW expansion. Go here for the LEGION page: http://us.battle.net/wow/en/legion/
Note the Beta Opt In button at the top left of the LEGION menu.

And the "Cinematic Teaser":
New Zone= Broken Isles
New Class= Demon Hunter
Level Cap of 110, includes a character boost to 100.
No weapon drops, instead every class will have a single persistent Artifact weapon that they can develop with drops or quest rewards throughout the expansion.
Class-specific order halls and followers, sort of a modified garrison.
No release date yet, but if you count forward six months from an open Beta announcement at Blizzcon in November, that would be April, 2016 ?
