This expansion was officially announced on August 21, 2009 at BlizzCon. It will release on Dec.7th 12:01 am. In this expasion, the water has been drastically improved, thanks to some impressive new shader effects. Water can now be configured to display reflections on its surface. This impressive change has helped to redefine many zones. Cataclysm introduces a new technology, terrain phasing, which changes the terrain over time as you complete quests or other requirements. Terrain phasing differs from regular phasing in that it affects the world environment.
