I hope this hasn't been posted already, if it has may the mods forgive my blunder and just feel free to remove this wall of text. Have a few mins 'til going out on business, thought I'd throw this up.
The official calculator tool has been released by Blizzard, and in it not only can we see the new talents but the spells given through choosing a spec:

I will mostly comment on the Ret side of things as prot seems mostly unchanged and I suck at Holy.
1. Seal of Justice no longer a talent but a spell. It's place has been taken by a talent that grants a 50% snare for 12 sec on a Judgment hit.
2. Speed of Light has been changed for other specs, for Ret it's now the speed boost + AoE heal as it was for Holy in Cata.
3. A new passive - your melee swings have a 25% chance to increase the speed of your next three melee swings.
4. A new passive - Judgment grants 1 HP and give a 4% damage increase on target.
5. Exorcism remains unchanged, but isn't tied to a talent anymore. It's just coded to activate only on melee swing procs.
6. Inquisition's max duration has been cut to 30 seconds.
7. Not sure but LAotL may have had its duration reduced. Was the sprint initially for 2 seconds?
8. SoB now makes haste affect HoW and Judge's cds also.
9. TV now has a cryptic tooltip saying that it consumes 3 HP to deal 39% weapon damage. Did they miss a zero? A bugged tip? Or does it mean it now scales linearly?
10. Divine Storm is a finisher that consumes 3 HP to deal 100% damage. Again as with TV, no scaling mentioned. Weird.
Otherwise, talents seem unchanged. Feel free to add something if I missed it.
Also, Holy paladins, feel free to add your changes too since I'm not about to start a discussion which I will understand nothing in =)
