Here's what we know so far:
4/14/10 - World of Warcraft - English (NA) Forums -> Cataclysm Class Preview: Paladin
New Paladin Spells
Blinding Shield (level 81): Causes damage and blinds all nearby targets. This effect might end up only damaging those facing the paladinâ€™s shield, in a manner similar to Eadric the Pure's ability Radiance in Trial of the Champion. The Holy tree will have a talent to increase the damage and critical strike chance, while the Protection tree will have a talent to make this spell instant cast. 2-second base cast time. Requires a shield.
Healing Hands (level 83): Healing Hands is a new healing spell. The paladin radiates heals from him or herself, almost like a Healing Stream Totem. It has a short range, but a long enough duration that the paladin can cast other heals while Healing Hands remains active. 15-second cooldown. 6-second duration.
Guardian of Ancient Kings (level 85): Summons a temporary guardian that looks like a winged creature of light armed with a sword. The visual is similar to that of the Resurrection spell used by the paladin in Warcraft III. The guardian has a different effect depending on the talent spec of the paladin. For Holy paladins, the guardian heals the most wounded ally in the area. For Protection paladins, the guardian absorbs some incoming damage. For Retribution paladins, it damages an enemy, similar to the death knight Gargoyle or the Nibelung staff. 3-minute cooldown. 30-second duration (this might vary depending on which guardian appears).
- Cleanse is being rebalanced to work with the new dispel system. It will dispel defensive magic (debuffs on friendly targets), diseases, and poisons.
- Holy Shock will be a core healing spell available to all paladins.
- We want to increase the duration of Sacred Shield to 30 minutes and keep the limit to one target. The intention is that the paladin can use it on their main healing target. That said, we would like to improve the Holy paladin toolbox and niche so that they donâ€™t feel quite like the obvious choice for tank healing while perceived as a weak group healer.
- We want to add to the Holy tree a nice big heal to correspond with Greater Heal. Flash of Light remains a fast heal, but will be more expensive to justify the cast speed. Holy Light will be the go-to heal that has average efficiency and throughput. Beacon of Light needs to be changed so that its benefit is letting the paladin heal two targets at once, not letting the paladin get two heals for the mana cost of one. Itâ€™s intended to save GCDs and targeting time, not mana.
- Holy paladins will use spirit as their mana regeneration stat.
In addition weâ€™re changing the paladin heal design to match that of the other healers. Holy Light is the middle heal. Itâ€™s very efficient, but not particularly fast and doesnâ€™t have a lot of throughput. Flash of Light will be the faster heal that costs more mana. (Currently paladins sort of flip the model around by having a fast, efficient heal.) Holy paladins can talent into an additional heal that is like a giant Holy Light. It might take three of these big heals (or two crits) to get a tank from deathâ€™s door back to 100% health.
Currently on live, Beacon of Light is a tool that allows paladins to target more than just the main tank. In Cataclysm if it just doubles their healing, it is going to be overpowered. We have two ways we might handle this and weâ€™ll experiment to see which feels better. The first is that Beacon only works on some heals, such as Flash of Light or Holy Light (but not the big one). An alternative idea is that Beacon increases the mana cost of a heal cast on a beaconed target, since youâ€™re essentially getting a double heal. Under this model, Beacon itself would cost no mana.

7/16/2010 - Dual Resource System Works like combo points.
Q: What is the goal when re-designing the paladin class? How do you plan to change rotations, talents, etc?
A. All of the paladin specializations will make use of a new resource called Holy Power. Holy Power accumulates from using Crusader Strike, Holy Shock, and some other talents. Holy Power can be consumed to augment a variety of abilities, including:
An instant mana-free heal: Word of Glory
A buff to increase holy damage done: Inquisition
A massive physical melee attack for Retribution paladins: Templarâ€™s Verdict
Holy Shieldâ€™s duration is now extended by Holy Power
Divine Stormâ€™s damage is now increased by Holy Power
We also introduced several new heals for Holy Paladins including Healing Hands (an AoE heal-over-time that is applied to all players standing near the paladin), Light of Dawn (a cone heal with a 30-yard range), as well as a new heal called Divine Light, which is similar to a priest's Greater Heal, and the new instant heal mentioned above, Word of Glory.

7/21/2010 - NEW TALENT TREES! WoW Talent Calculator - Sigrie
Looks like Seal of Wisdom and meleeing for mana are still fair game:
Holy signature abilities:
Seal of Insight: Fills the Paladin with divine power, giving each single-target melee attack a chance to heal the Paladin and restore 4% of the paladin's maximum mana. Only one Seal can be active on the Paladin at any one time. Unleashing this Seal's energy will deal Holy damage to an enemy.
Paladin - Holy
Invokes the power of the Light to protect and to heal.
There is no Divine Illumination. Divine Favor is 100% chance to crit on your next heal with a 1 min cooldown.

7/30/2010 - New Mastery
The current Holy paladin mastery:
Your healing spells also place an absorb shield on your target for X% of the amount healed lasting 6 sec. Absorb increased further by mastery rating.
