This is what I got so far for a pve dps spec:

Blood Build

Now 1 question remains, Rune Tap or Corpse Explosion?

Edit: I'm new to this, so I couldnt really do the link until now, implemented the link to my specRune tap....i love the instant 20% hp heal (with improved)
Ok cool thanks
I don't believe you have thoroughly researched your build...

Dancing Rune Weapon is bad for DPS early on, the gargoyle is much better, also Blood-Caked Blood is a fantastic talent early on. If you are trying to focus on DPS also why go with Shadow of Death? You don't plan on dying do you?
Shadow of Death gives +2% str also,

but its just so good to know that when you die, you are still in the fight, giving you an edge if the boss does somekind of I-win/Wipe spell

Prince and kiljaeden does some kind of novas which are examples of these I-win/Wipe spells

Many bosses have them, and as so I think its a usefull talent.
But I haven't been on the beta, so I cant say how usefull this will be in wotlk
I will have to disagree with Reeku about the Dancing Rune Weapon. As far as I've understood, it basically doubles your damage for 10 to 40 seconds. However, I haven't been in the beta, so I might be wrong.
