While the actual news isn't nearly as dramatic, it seems like the Arena Gladiators have taken a turn for the worse. From Season 2's Merciless, which wasn't so bad, and Season 3's Vengeful, which was alright, we progressed (regressed?) to Season 4's Brutal Gladiator, which was brutally ugly. The first Level 80 Arena gear has shown up on wowhead, and it's hateful. No, really. The new Arena gear is called Hateful Gladiator and it's actually pretty sweet, with single pieces conferring up to 1.3k health.
It's too early to tell if the stats will keep until release, but it's safe to say that players should already looking ahead to the end of Season 4. Blizzard has stated that there will no longer be any further iterations of Level 70 Arena gear, meaning that Level 70 Arenas will end on an ugly note. Curiously, even the Honor-bought gear such as rings and amulets, are also called Hateful Gladiator (who thinks up of these names, seriously?) instead of Guardian or Vindicator. The new Hateful Gladiator items still have placeholder graphics and are seem to be in Beta merely to help test the broken Lake Wintergrasp. For now, we PvP addicts to content ourselves with the small nugget that Season 5 is going to be a Hateful one.
