So i've been going around some forums recently, mostly this and EJ. From what i've seen as of now (10/7/10) As a warlock (non-demo) it seems like Destruction is the way to go. Even with the nerfs it still seems to be pulling ahead imo.
Spec:

-------------------------------------------------------
Glyphs:
Prime:
Conflag
Immolate
Incinerate
Major:
Life Tap
------ Other glyphs choices for Major/Minor Don't matter ------
Priority:
Soul Fire (over 80% w/o Buff)
Immolate
Bane of Doom (Bane of Havoc for Multi-Target
Conflagrate
Instant Soul Fire
Chaos Bolt
Searing Pain (If under 50% and aggro
CAN handle it)
Incinerate (If over 50% or aggro
CAN NOT handle it)
-------------------------------------------------------
Notes: (from Gherkin's 4.0.1 Post)
-Summon Infernal/Doomguard when possible for DPS boost.
-Same as demonology for Shadowflame [Shadowflame in Melee = DPS boos]
-Expect Searing Pain to be nerfed or incinerate to be buffed
However i did find that Infernal is more AoE pet DPS while Doomguard is more single target DPS (May be wrong as I am going from memory)
Aggro for Searing Pain:
With
Searing Pain crits sub 50% and 250% increased threat, you will be pushing up the aggro meters quickly. You should manage to be fine as long as
Soulshatter is used well. If you are pushing threat and can't reduce, you can resume using Incinerate.
Apparently as of now, the Searing Pain crits are a DPS boost compared in Incinerate sub 50% currently. (may be nerfed pre-release)
-------------------------------------------------------
As I see mistakes or changes pointed out on forum i will try to update this post.
