MMO Champion has a new post up today with details on several Cataclysm changes, including Archaeology, Reforging, and (what really caught my eye) the new water engine.

Considering that water-filled areas are supposed to be a big deal this expansion, it's no surprise that they took this opportunity to update the water. Now, will they be providing us with scuba gear?
