Is Curse planning to try to get addon authors beta access as they have in the past?
WoW Interface is working on it.
Anyone have any news on this?
Don't recall ever seeing Curse do that; lots of 'new' addons show up over on WoW Interface around beta-season for just that reason.
They have done it for years. They used to allow you to purchase a key as an author on their author rewards page. For Legion they asked for you to enter your battle.net email address, and they sent that list to blizzard.
