Eyonix commented that a Linux version of World of Warcraft could be a possibility in the future. There seems to be some issues of an internal Linux testings connecting to the server. Blizzplanet initiated the Wow on Linux petition sometime ago. Blizzpub facilitated to us a script to gather signatures for the petition for Blizzplanet under the condition of hosting the script themselves—until Blizzpub … removed our participation or any reference about Blizzplanet involved in the petition. Yet, we are glad that a Blizzard Representative have given good feedback reporting a possibility of a Wow Linux client in the future. Read more details at the Official Wow Forums.
