It's official: registration for the 2010 World of Warcraft Arena Tournament is now open! Like last year's arena tournament, players will participate on regional tournament realms -- separate from live realms -- for a spot to play at the live events. The arena tournament will use the 3v3 arena format for teams, and the regular arena season on live servers will not be interrupted by this event. The cost of registration is one payment of $20 per eligible World of Warcraft account. For more information on eligibility and restrictions, check out the Arena Tournament rules page.

This year's cash prizes, including prizes awarded at both the regional finals and world championship, amount to over $200,000. But even if you don't win the big prizes, there's still something out there for participants -- players who have participated in at least 50 rated tournament games on one character with the same team will be eligible for Murkimus, the gladiator murloc pet that players may remember from last year's tournament. Please note that as of patch 3.3.3, Murkimus is an account-wide pet that will apply to all WoW characters on your Battle.net account. Players who have a character in one of the top 1,000 teams and have participated in at least 100 rated tournament games during the last four weeks will also receive the Vanquisher title for their live characters level 71 and over.

While the news may be good for players that missed out on last year's games, some have expressed disappointment that there was no new pet and title for this year. Zarhym addressed this in a post on the Arena Tournament forums:

 Zarhym While it would be cool to provide a new pet, we're not necessarily trying to encourage as many people as possible to pay $20 and sign up for this tournament ultimately because they want a new pet. It's a nice perk to encourage people, but we don't want the Arena Tournament to be a more complicated version of the Pet Store. We want players who are serious about competing to sign up for the tournament, not just a reason to take in more money through offering a new vanity pet with each new tournament.

So for those of you looking for a new pet -- sorry, looks like that's not in the cards this year. But for players who missed out on the pet last year and players who would like a chance at the cash that Blizzard is paying out, you can sign up for the fun and games on Blizzard's website.
