I dont believe for a second that the classic server project is in its early phases like blizzard claims it to be, there is ABSOLUTLY no way they would announce vanilla unless they knew FOR SURE that they can make it happen, how can they be sure enough to announce it? by actually doing it. I dont think they would NEVER EVER announce it if it was only a concept, idea, or a hope that they can make it happen.
I believe blizz has been working with the nostalrius team ever since they met up. I believe they decided to do vanilla servers back then already, but couldnt announce it at the last blizzcon because the project was in fact BACK THEN, in its early stage.
Think about it, EVERYONE was expecting vanilla announcements blizzcon 2016, and when it didnt happen, everyone lost hope, everyone thought it would never happen and you could say the hype went down quite significantly, significantly enough that NO ONE was hoping for Vanilla announcements this blizzard. Blizzard is not stupid, if there was a possibility, they would had announced it last blizzcon, ride the hype and also redeem them selves, for shutting down Nostalrius, but they couldnt.
The way Allen Brack talks implies that he is hiding something, he is using words like:
- "We THINK we have a way to run the Classic servers"
or
- " we THINK we have a way to have the old WoW version work on the modern infrastructure and feel really good."
Like i said earlier, there is no way you would announce classic servers to a community as fierce as the WoW classic community if you werent 100% sure u can make it work. I dont think they want to repeat the situation and backlash that was created by announcing Arena PVP in Diablo 3 and not come through on that promess, different game, but im guaranteed they learned a lesson from that.
So based on this i believe that Classic is more "ready" then they lead us to believe, now what are they plans to release it with the new expansion coming and all i cant say my guess would be inbetween Legion and BFA, specially if we have as much time between the expansions than we did with WoD and BFA.
