Leak said Prepatch on October 25, Launch on November 28
Would make perfect sense, really. 2 weeks of new race/class and to get used to the new UI changes and Talent tree changes, as well as giving time to farm the dungeon portals on the Evoker for those that are dedicated enough. Then two weeks of pre-patch event alongside all the other stuff mentioned before.
The world revamp dream will never die!
That feels a tad short, I'd expect them to aim to launch in time for christmas sales but not necessarily much longer before. like prepatch mid/end of nov, release by mid december.
I'm not disputing the authenticity of whatever leak that is mind you, but even if they plan for "release on date X" at a certain point in time it doesn't mean it's set in stone, especially if it hasn't been announced officially
Release date has to come very soon. Within the next 2 weeks we should know it.
Everything else from the leak proved to be true, so I'm afraid it's gonna be end of october...
They will have to announce it at some point though..
It doesn't matter if pre-patch is longer because they will only release Evokers 2-3 weeks before Dragonflight release like demon hunters who were not available at the start of pre-patch. They did something similar for Demon Hunters and made them a tier set to get from tokens in HFC. Think of this as a future investment. The unity is general effects so all future classes added to the game will be using it.
