I think the question to ask is whether they will cut the last patch or not so they can keep the 2 year expansion cycle that they have been pretty consistent about. If this patch lasts 8 months, 9.1 patch lasts 7 months, 9.2 lasts 7 months, then there is only 2 months left for 9.3 to hit the magic 24 month expansion duration. Blizzard seriously fucked up here cause they are basically required by shareholders to have a box release on 2 year cycle and yet players will be pissed off if they don't get 9.3.
