Had a discussion with guildies today about the Zulian Tiger just about 5 minutes ago (one particular guildie has yet to see it and is worried he won't get it before Cata drops).
One guildie chimed in that ZG is getting recycled and will be moving to Echo Isles as a new troll raid in Cata (though he was unsure about the mounts moving with it). He said he heard about this at Blizzcon. I hadn't heard anything like this and was wondering if anybody had any information about it?
