There's been a lot of talk and speculation about the World of Warcraft's Arena Tournament season two gear. World of Raids was able to get a complete list of the set bonuses from WoWHead.

Basically the names of the Arena 2 gear are still the same as the first batch, just affix a prefix of Merciless Gladiator's (instead of just Gladiator). Some of the pieces grant the same bonuses and all class sets get +35 Resilience for two pieces. Here's the list:
