Juicy Lore Tibits from the Dev Twitter Chat.
Q. What did Yogg-Saron have to do with the Lich King? It seemed like a strange tangent to make in the middle of the expansion?
A. Did you do the quests in Icecrown? Quick answer: the existence of an Old God in Icecrown had a lot to do with the ability for mortals to become corrupted.
Q. With the Lich King defeated, in Cataclysm, will the Plaguelands be green and beautiful again?
A. Western Plaguelands will finally be free of the plague in Cataclysm. It’s hard for the Scourge to survive without their beloved Lich King. I guess this means we need to rename the zone?
and
Q. Will there be any type of water mount, like, submarines?
A. We actually have two brand new subs that we made for Cataclysm. These submarines will be used as transports. We have one for gnomes and one for goblins. The subs are huge too! Both are about the size of the Gunships from Icecrown.
Which is kinda lorey since we haven't seen subs since Warcraft 2
