Though season 4 is not upon us, I am fairly certain I saw some new blue-quality lvl 70 pvp gears bein introduced with the next patch. Supposedly, you buy them with gold... and there's a rep requirement...
From the first line of the Items section of the 2.4 patch notes:
Quote:
Players will now be able to purchase level 70 Superior quality PvP items from reputation vendors.
I saw the gears somewhere official... but i dont remember now... you could prolly find them on yer own if you looked hard enough.
Cheers,
