Shadow priests got no leeway in terms of spent talents on this tree. In fact, the cookie-cutter spec is looking like we will have to take every talent in the shadow tree minus two points in our threat reduction to grab Inner Focus. I think Blizzard should make more shadow talents flavor talents and not raw dps upgrades to help mend how bloated it has become. I am very excited for the PI+Chakra Smite spec that I'm sure many will be testing once beta comes out. Seems like it will be good for automated spot heals while still maintaining decent damage output. I noticed the GCD reduction to Holy Nova that this smite spec would take for AoE as well.
I don't like how a hybrid sub spec (smite) will have a proc and a damage CD (Surge of Light / PI ) and Shadow; the main damage spec will not.
