Since nobody else has posted it, here's a thread to discuss 3.0 and Wrath shit for Warlocks.
So far it looks like Destro is going to be the strongest DPS spec yet again, however it is becoming less brainless. Instead of putting up a curse and spamming shadowbolt until your fingers fall off there is some actual thought and precision required to achieve the potential of the spec. Preliminary tests by Profanitie from Exiled were using this spec:

Pulling a consistent 2.8-3.1k depending on if Bloodlust was up or not. This is at 70, obviously, and the march to 80 affords more talent points. However, Warlock relative strength should remain the same or increase during 3.0. If numbers can be pulled at 70 like this in Sunwell gear then 80 should prove to be interesting.
Affliction still looks to have scaling issues with the Haunt nerf. However, it's generally the more complicated tree, so we'll see if anything develops.
Demonology looks like it has potential to be strong as long as pet management is good. One thing to look into is how much spell power can reasonably be achieved (IE, without gimping other stats). Wrath of Air totem has a max rank in the xpac that gives 280 spell damage, so Demonic Pact becomes better than this totem once 2900 spell power can be attained. Obviously this scales with the locks gear, but it will be necessary to weigh how much extra damage is gained from the raid wide boost vs how much DPS, if any, is lost by speccing demo.
