8.3.5 could give us few questlines for post N'zoth world to wrap up all things, lower requirements for essences (or just make them account-wide, it's late expac anyway) and maybe introduce Lightsomething Undead + Alliance race based on Worgen model. If we will have 8.3.5, it's almost 100% it will launch on March - so far EVERY BfA patch launched less than 30 days before end of quarter and June would be too close to 9.0.
