Curse has the news that the 2.1 PTR has been updated, and the biggest change is that
PvP epic gems have had their honor costs reduced, so if you're saving up points for an Inscribed Ornate Topaz, you'll be happy to hear that it now only costs 10k honor points (and the disappointment of only one of your children when you're too busy PvPing to go play catch with them in this Spring weather).
And finally, the Mongoose enchant (which adds a chance-on-hit agility and attack speed buff) has had its look changed. Video of the new, really strange, spiky look after the jump. The old one was apparently too glowsticky. RAVE ON!
Update: Apparently word from Eyonix on the forums is that the changes will be reverted before 2.1 goes live (thanks, Greg!)
