The following was apparently taken from a EU Forums Blue post which was soon deleted,

• The Tier 4, Tier 5, Tier 6 and all Gladiator Sets have had their Spell Damage removed and the points have been reinvested in other stats, such as Strength and Critical Strike Rating.
• Exorcism mana cost reduced.
• Holy Wrath mana cost reduced.
• Hammer of Wrath mana cost reduced.
• Pursuit of Justice (Retribution) is now 3 ranks and increases movement speed by 5/10/15% and also reduces the chance you’ll be hit by spells by 1/2/3%.
• The benefits of Improved Seal of the Crusader (Retribution) have now been implemented in the base spell. This talent now gives the benefits of the Sanctified Crusader talent instead.
• Sanctified Crusader (Retribution) is renamed to Sanctified Seals, and now increases your chance to critically hit with all spells and melee attacks by 1/2/3% and reduces the chance your Seals will be dispelled by 33/66/100%.
• Two-Handed Weapon Specialization (Retribution) now also reduces threat caused while wielding a Two-Handed Weapon by 8/16/25%.
• Vengeance (Retribution) duration increased from 15 to 30 seconds and now increases Healing done as well.
• Seal of Command (Retribution) now does 85% Weapon Damage, but is no longer affected by Spell damage.
• Judgement of Command (Retribution) now does holy damage equal to 25% of your Attack Power and 50% when the target is stunned or disoriented and is no longer affected by Spell Damage.
• Crusader Strike (Retribution) cooldown reduced from 10 to 6 seconds and does 110% weapon damage instead of weapon damage plus 40% of your Holy Spell damage.
• Vindication (Retribution) frequency and duration increased and now reduces all attributes by 5/10/15%.

Threat reduction issue is resolved here with Two-Handed Weapon Specialization. A little raid utility with Vengeance increasing Healing done. Raid viability is definitely improved here.

Note that this is just a rumor and not confirmed, so keep your fingers crossed. In the meantime, I’m going to get me some Retribution gear.
