Blizzard has announced a Midnight deep dive along with a live Q&A afterwards on October 1st:
I went ahead and asked a question for the San’layn megathread here:
“Seeing as we’re uniting several Elf tribes and eventually going back to Northrend in The Last Titan, and that San’layn were former Blood Elves who were turned against their will into vampires, will we see San’layn appear in Midnight, have them be one of those Elf Tribes we unite, and then help us in both Midnight and The Last Titan?”
Wasn’t really easy to word it, but I felt it was worth an ask. The whole “Uniting the Elf Tribes” theme hasn’t been defined and I wanted to make sure attention was brought to San’layn with that idea. Moreso when we’re going to Northrend again after the next expansion. While I’d be surprised to see any questions I asked answered, it at least draws attention to all the support for playable Horde San’layn.
I did try to ask questions for playable race request megathreads that would have a vested interest in the next expansion. It’s usually what I try to do with these Q&A threads. Unfortunately, I’m unable to do that with every playable race request megathread, usually if I can’t tie them to an expansion.
Still, I wanted to try to give who I could a chance to have a question asked and show interest for that race to become playable, so for any I missed, I do apologize in advance and if anyone can think of any questions for the megathreads I missed, please post as well.
If anything of particular interest does come from the Q&A, I’ll be sure to post about it, but it’s best to keep an open mind. Especially since there are plenty of great questions in there. 
–Still dreaming of playable Horde San’layn as a full race!
