Here's a list of what I've found so far. Not all of these are new, strictly, but they are all from randomly generated items, where some of them (Aligned) only showed up on named stuff before.
+3 Natural Armor - Ring suffix
Orderly - Weapon prefix, Gives: True Law, Strength Sapping
Pandemonium - Weapon prefix, gives: Screaming, Thundering, Roaring
Poison - Weapon suffix, 1d6 poison damage per hit, applies "lesser dex poison" - 1d6 dex damage on a critical hit
Virulent Poison - Weapon Suffix, 1d6 poison damage per hit. +1d10 poison on a crit for x2 weapons (etc), Strength Poison, Virulent: 1d6 strength damage on crit
Absolute Chaos - Weapon prefix, 2d6 damage to all non-chaotics. UMD: 26 to use if not Chaotic
Aligned - Weapon prefix, gives Good/Evil/Law/Chaos DR bypass.
Telekinetic - Weapon prefix, On Crit, DC 17 or be knocked down
Icy Depths - Weapon suffix, Gives: Tidal (1d4 damage per hit, fire subtypes take double), and Icy Blast (as Greensteel)
Desert Sand - Weapon prefix, Gives: Flaming Blast, Slicing Winds
Sun's Fury - Weapon suffix, Gives: Flaming Burst, Brilliance
Acid Burst - Weapon Prefix...yes, lootgen acid burst.
Debilitation - Weapon suffix, Gives: Weakening, Enfeebling, Shatter +10
Rebel - Weapon suffix, Gives: Absolute Chaos, Good Blast
Destroyer - Weapon suffix, Gives: Absolute Chaos, Evil Blast (like Good Blast on Tier3 greensteel, but works on all non-evils).
Annihilating - Weapon prefix, Disintegration Proc, description matches a Dust II greensteel.
Buttressing - Armor Prefix, Gives: DR 2/-, False Life, Natural Armor +2
Glowing Prisms - Armor Suffix, Gives: Fire/Cold Resistance (the 10 point versions)
Potency - Armor Prefix (this one may be bugged): Universal Spell Power - Increases damage of 8th level and below spells by 30%, does not stack with other items or potions.
Light Guard - Armor Prefix, 1d6 light damage to attackers when hit
Energy Deflection - Armor Prefix - The version I saw gave 5% acid damage absorption, this may come in other flavors.
Energy Ablation - Armor prefix, 10% absorb, found Acid, Fire, Cold so far (not on the same item though). Same prefix name.
Thorn Guard - Armor Prefix - Like bramblecasters
Force Burst - Shield Prefix ...yea, force burst. The one I saw also had Pure Good as a suffix.
+15 Minute Seeing...Prefix, on GLOVES
Elemental - Armor (Docent) Prefix - Gives: +10 Inherent resist to Fire/Cold/Acid/Lightning. Stacks with everything except Inherent Resist +10.
Warding - Armor Suffix - Gives: Spell Resistance (22), and Resistance +4
Special Note:
+3 Glaciation Quarterstaff of Greater Healing Lore - Spellcasting Implement 9 (two handed weapons get x3 multiplier?), Glaciation 78, Greater Healing Lore, Spell Focus Mastery +1 (yes, just like the Napkin), 5/5 (Recharge Per day: 2) CL1 Knock.
There are several other quarterstaves like that. They all seem to have bonus spell effects above and beyond what the prefix/suffix would indicate. One has Greater Abjuration Focus and 3 (1/day recharge) of CL3 Gust of Wind. Another had Arcane Lore (!) and clicks of Magic Missile.
Rebel and Destroyer with Chaotic Good and Chaotic Evil mean there will be equivalent versions for the other extreme alignments, with Absolute Law+Good Blast "Of the Crusader", and Absolute Law+Evil Blast "Of the Dominator".
+6 Elemental Planeforged Docent of Warding, with the above mentioned effects, but here's the odd bit: Minimum Level: 25. Absolute Minimum Level: 22...erm?
I found a -lot- of caster modifiers on armor that never appeared there before. Major Lightning Lore Breastplate, or a Spell Pen VIII Tower Shield, for example.
