As I was RSS Reader-hopping this afternoon at work to make the day go by faster, I noticed a post on WoW Insider about the WotLK beta Patch Notes.
I have made an effort to wipe up the drool and copy for you here the part that pertains to Warlockery (any emphasis is mine):

Warlock

* Aftermath (Destruction) - Now a 2-point talent, down from 5.
* All demon abilities and spells will automatically be learned as pets gain levels. Demon Master trainers will be removed.
* Blood Pact now works raid-wide (not just in party).
* Cataclysm (Destruction) - Now also increases your chance to hit with Destruction spells by 1% per point.
* Curse of Recklessness will no longer prevent Fear effects, only prevent NPCs from fleeing (e.g. at low health).[Shastarian: boo! No more Fear-kiting in Instances!]
* Dark Pact: Tooltip updated to be more consistent with other similar effects.
* Demon Armor - Now increases healing done by spells and effects by 20%, but no longer has in-combat health regeneration.

* Unstable Affliction (Affliction): Silence effect reduced to 3 seconds, down from 5.

And also:

The combat log now differentiates between a spell failure due to resistance and spell failure due to missing the target. Where once both events reported as a resist; a spell missing the target is now reported as a miss.

I really, really, REALLY want to get in on this beta!
