So apparently the Horde leveling is released for alpha in the next few weeks. Assuming that means less than a month, lets say three weeks, and we’ve had three weeks for the Horde leveling, and they’re also doing three weeks per zone, I’m assuming this Alpha goes into early summer, maybe July at some point, or August.
Given Shadowlands is Spooky, I’m going to assume they’re going to tie Shadowlands to Halloween/Day of the Dead, either slightly before or slightly after. Maybe prepatch late October and release early November. Usually prepatch is a two week period, more or less.
So that gives us at least 3 more months of Alpha and probably 2 months of Beta, assuming I’m right in my guesstimates and Blizzard being corny re: Spooky Xpac with Spooky IRL Holiday.
