For the people wondering, here's how I predict the Feral talent bonuses to look:
1. Increased Agility.
2. Increaed Critical Strike chance (threat/Savage Defense for bears, more Attack Power/Crit for Cats.
3. When in Bear Form, (insert nice Bear bonus here). When in Cat Form, your critical hits do xx% more damage. Or something along those lines.
Really, it's not that complicated.
