Again, it will probably just be as any other horde/alliance situation most likely. Which is basically pack up and leave when the story is over or you simply move to the next content. I would honestly be fine, with a Gilneas treatment, given that sure you can peak around and such, but not really interact or put your hs there. It would be for RP purposes only. Also.. people forget the alliance/horde are currently at peace, but this is warcraft and that situation can change very easily.
If it ends up being like Gilneas and the like, it still wouldn't be called neutral really. Turning a actual wow longtime horde/alliance capital into a pure neutral city has never happened before and I honestly don't see it shaping up to be that way at all with what we know. I don't know how people can jump even further with literally zero info.

Read my reply to Tanaria, I know you haven't read anything so far looking at your comments on the last few pages, but at least try it for once without being bias. So far, I have seen nothing but trying to be patty comments or the ha-ha ones coming from you.
That is so far, the most likely outcome. Remember this is done with one line of info on midnight and what we have seen with Gilneas.

Maybe, you should do some reading yourself, you have been wrong with everything so far
Blood elves are just renamed High elves silly. Those are the OG high elves. Not those silly SC elves.
Anyhow with the customization option available for blue eyes for blood and void elves, there is simply no difference there. The high/blood elves have been cured a long time ago as well. The high elves you are talking about (the Silver Covenant or the unworthy ones according to Elisande), simply don't have a claim to their homeland, their claim is sentimental rather than legitimate. That being said, I am glad the name high elf doesn't mean much anymore or rather has been solved and are playable so to speak.
