Or is there more? during the PTR the cataclym pre-event was turned on, but im wondering if blizzard left any surprises for us.
I know that Zarhym said their were 4 stages but im not sure what the definition or a stage is by blizzard. Hopefully they did.

Im curious to see what you guys think :P

Edit: also Zarhym said our minds will be blown by the time 4.0.3a comes around, but many say that the scourge invasion was much more fun
than the current event
