I really question this logic though. As someone who played with a large group of friends from Beta to TBC, none of us would even consider picking up WoW in its current state. Obviously this is a very small sample size, but I talked to many people when playing on Nost that felt the same way.

I do not see how they would be splitting the userbase, when many of the players of this server wouldn't even consider returning to Blizzard's current product.
