Right, i've been following this thread (and the others) for a while now. I don't know anything more than your standard forum browser here, but i've played since 2005. I've monitored these forums for the vast majority of that time, i've watched (Live) every expansion reveal to date. I've read so many speculation threads, and i'm probably one of the biggest lore nerds on this forum. I'm going to throw some bold predictions out, and you can feel free to save this post and come back to QQ when i'm wrong on Friday evening.
At this point, i predict the following will happen / is true.
- The Bolvar cinematic picture is legit.
- The expansion is called World of Warcraft: Shadowlands.
- The next Hero Class will be the Dark Ranger.
- N'zoth will have a cinematic after the ingame cut-scene where somebody traps him inside of the dagger.
- The Shadowlands leaked map design is legit.
We will have our answers soon enough.
