Been peeking through the MPQ files with the PTR patch, and I've found what I assume is going to be the names of the non-class specific sets from Sunwell Plateau -- then again, these could be for Season 4. Either way, I find the names uneventful;
Opportunist's Battlegear
Seer's Mail Battlegear
Seer's Ringmail Battlegear
Seer's Linked Battlegear
Stalker's Chain Battlegear
Savage Plate Battlegear
Crusader's Ornamented Battledgear
Crusader's Scaled Battlegear

EDIT: Been finding all sorts of cool stuff, I'll just update this post as I go.
Sunwell Exalted Necklace -- "Your spells have a chance to call on the power of the Arcane if you're exalted with the Scryers, or the Light if you're exalted with the Aldor."
References to a Holyform -- "Assumes a Holyform, increasing healing dealt by $s1% and reducing melee damage taken by $s2%. Holyform lasts until cancelled."
Enchant Deathfrost -- "Permanently enchant a weapon so your damaging spells and melee hits occasionally inflict an additional 150 Frost damage and reduce the target's melee, ranged, and casting speed by 15% for 4 sec."
Not sure if this was confirmed before, but there's a lot of "Brutal" items, i.e. Brutal Libram of Justice, Brutal Libram of Fortitude etc.
Quick Dawnstone, Forceful Talasite & Reckless Noble Topaz are the names of the new gems, can't find the metas
Legendary bow -- Increases ranged attack speed by $s1%. Does not stack with quiver or ammo pouch haste effects.
Weapon Oils just for Sunwell Isle, Blessed & Righteous Weapon Coating -- While applied to target weapon, wielder has a chance to regain $ mana on each spell cast. & While applied to target weapon, wielder has a chance to gain $ attack power on every melee or ranged attack for $45401d. Only functions on the Isle of Quel'Danas, on the Magisters' Terrace, and on the Sunwell Plateau. Lasts for 1 hour.
