Some notes here, before we go: as of today, we have found out that powershifting will be no more. So keep that in mind when looking at the build. We also know that Omen of Clarity will be buffed quite a bit in its proc rate. And...we'll be getting some other goodies. But bah, why speculate? Why wait? Let's go to the cat!
This has got to be one of the oddest builds I've ever done. So...I expect a lot of questioning this time around :)

I'm not going to go into every single talent here, but just go over some of the choices that seem odd.
The first odd choice is going with both ferocity and feral aggression. The fact is that for raiding, thick hide and feral instinct do absolutely nothing for a cat. Feral aggression, while not particularly great, is better for cat dps with the new ferocious bite mechanics. Even if you use ferocious bite once in a fight, this will be better for your dps. But I'm not happy with it, and I'd never do a build with this on the off-chance I'd be tanking anything.
The second odd choice is to not go for Natural Shapeshifter/master shapeshifter in the resto tree. Natural Shapeshifter is not at all useful now that powershifting is out of the equation, so we're left with spending 5 talent points to get 4% crit. That's not worth the talent points, so we skip it. At 80, of course, it would get taken.
Feral Swiftness, while awesome, is not required for dps either. I'd miss this a ton, but for raiding it's not required. If you have another druid in your raid that can put up Faerie Fire you can skip the point there and go put it back into swiftness.
Primal Precision is only good for the dodge component for DPS, but even so it's 2 points for 2.5% fewer dodges, which is pretty good on the DPS/talent point ratio. The refunding of finishing moves is gravy.
Savage Fury is worth about 1.5% more overall DPS at max rank. This is based on the percentage of mangle damage from various WWS. That's .75% DPS/talent point. It's not as good as other talents for DPS/talent point ratio, so again it gets skipped. It'd be brought back at 80.
Improved LotP is going to be a raidwide buff, so chances are that this is one of the reasons a raid will bring a feral. Does nothing for your dps, but should help your raid's survivability a bit.
King of the Jungle is going to be one of the ways powershifting's utility is replaced. Absolutely a requirement for any serious cat dps. 60 energy every 30 seconds will be on par with the 2-piece tier 4 bonus.
Infected Wounds also does nothing for cat dps.
Improved Mangle is worth about 2% more overall DPS at max rank - this is based on the value of the 2 piece T6 bonus, which is also worth about 2% more overall DPS. That's about .66% dps per talent point, which just isn't that good. This may not make the cut at level 80; it's still lower per point than master shapeshifter.
Rend and Tear barely makes the cut. Assuming that you're only hitting bleeding targets with shred (which is a fair assumption given the standard rip->mangle->shred to 4/5cp cycle) we're talking roughly a 4% increase in total damage done, which makes this .80% DPS/talent point. That's pretty close to natural shapeshifter/master shapeshifter, so it's more a matter of preference. I picked it because once again - if you ferocious bite at all, this will pay off a bit.
Personally, I'd never choose this build because it's not useful enough in the general sense. You could not reasonably tank a boss with this unless it was massively outgeared; too little armor, dodge and threat gains. But for cat, it's about as strong as I think it can be at level 70.
