After Blizzard's latest press release, we know that Cataclysm will be released in early December. We already know that there will be at least one patch that precedes the expansion. The period of time between patch 4.0.1 and the expansion's actual launch is a time of transition, and it's rapidly approaching. The transition phases of The Burning Crusade and Wrath were rocky to say the least; it's safe to say that that we're looking forward to exciting times.
Many classes are hurting pretty badly on the PTR for patch 4.0.1 right now. Blizzard had the great idea of temporarily granting rogues Cloak of Shadows as our 31-point subtlety talent back in patch 2.0 to help us deal with the souped-up casters of that era. A similar change could be used to give retribution paladins access to Inquisition (at the cost of Zealotry) to bolster their damage until Cataclysm. Luckily for rogues, we were on the receiving end of the latest "damage pass." Several of our core abilities were granted significant damage and scaling bonuses to keep us competitive in a pre-Cataclysm world.
