That's right, Eyonix has stated that Arena Season 4 will be starting on June 24, 2008. This season brings about some interesting changes, including among them a personal and team rating reset. 

A fun site to play with, this simulates the random loot aspect of Kil'Jaeden and Illidan. I decided to see what a years worth of farming (You can refresh the page to simulate a week/lock) would get me. I ended up with 5 MH Warglaives, 4 Thori'dal's, and 0 OH Warglaives. I also noted that (as a hunter, it interests me) Illidan's bow dropped about once every other month, and (as it looks cool, and tanks would want it) Illidan's shield dropped twice only. Back to back weeks, as well. I did, finally, get an OH Warglaive, 3 weeks into the "new year".
