The talent trees look quite convincing to me and the other dragon race leak shared by Corin looks like a more polished version of what was shared earlier, indicating the earlier screenshots may have been severely out of date.
I don't think Corin is necessarily just bullshitting everyone even though he shared that one screenshot from the private server. He could be getting his info from somewhere else (a Discord server or something) and could have been the one that got tricked by that image and decided to share it here, thinking it was from 10.0. I think the first image he shared (linked above) actually looks quite convincing.
But yeah, maybe 4.25 is a bit too generous.
So apparently there are three IGCs coming in 9.2.5:
TQG- The Queen's Gift, Winter Queen and Tyrande
???- Sylvanas, Darithur and Anduin in the Maw
LQF- ?????? but may very well be Lordaeron Queen Finale or Lordaeron Questline Finale (matches with the encrypted Calia model: could be HD Calia)
So we have one questline for Nelves and probably one for Forsaken. The Tirisfal stuff may not be Darkfallen after all but instead they are questlines relating to new capitals for Nelves and Forsaken.
World revamp bros....
One thing im guessing that we will be probably seeing vrykuls one way or another, i doubt as playable even tho i wanted it since wotlk but they're too big, although they could make them the same size as zandalari and i wouldn't mind.
Rexxar should have a role too.
Okay gents, 1 hour 30 min left. Time to start saving comments for the "I told you so" and "Sorry for doubting you" rounds
