Sounds interesting in some parts - which are (imho)

...Our new plans for Soul Shards will help here. We want to make them a core mechanic instead of a minor feature that can be neglected at best and feels tedious at worst....

We’re happy with the relative damage done by Affliction and Destruction. Depending on which Lich King patch you look at one or the other are slightly on top, but they’re close. Demonology still seems to lag a little behind. We think there is still room for a strong Felguard build in there. It might be that the pets still require too much management or it could just be that the rotation isn’t as interesting as the ones Affliction or Destruction use right now. Demonology suffers from a little bit of the same problem as the Beastmaster hunter, which is when the pet is such a big part of your damage you are crippled in moments when the pet is killed or ineffectual.

Except for a brief moment early in Lich King, warlocks have been under-represented in PvP and we want to see more of them. We don’t want to get there through fear bombs, though. In fact, we think the damage locks can do is in a pretty good place. The problem is survivability, especially when stunned. Now some of the 3.2 changes are going to chill out damage across the board and we are increasing the survivability of pets in PvP. Both of those changes should help warlocks, who historically have been a little better in endurance fights than quick scrums. If those changes aren’t enough, we’re prepared to make additional ones....

...As we have hinted on occasion, we have a revamp of the entire SS system in the works. ...the basic idea is that shards provide a combat boost when needed without becoming a resource that needs to be farmed. Currently too many of the shard abilities are maintenance-like things such as demons and stones. Blowing a stone should be a big deal -- an exciting moment. We want to make shards fun and remove the hassle, but we want to make them a core part of the warlock experience and not a marginalized feature. ...

...We are going to lower the cooldown of Soulshatter to three minutes. We don’t think the shard cost is a big expense in PvE situations. Threat-dump abilities are tricky to balance. We don’t want these spells to feel rotational -- you aren’t supposed to do say Curse of Agony, Immolate, Soulshatter, Curse of Agony, Immolate, Soulshatter. They are there for emergencies....

...We never wanted it to feel like it was stupid to attack the pet -- like they were so unkillable that you just have to endure damage from the pet while you chase down the lock. You have to remember that locks were once really dangerous in PvP (this was back when we added resilience for DoTs) and so everyone was nervous about making their pets too powerful. It’s just incredibly frustrating to be on the other end of that and finally get a pet down only to have to then face the warlock. However times have changed and we think pets are too fragile now. We tried buffing their health a few times, but we think it’s finally time to add resilience to pets and fix it right.
