To my knowledge there has been no information leaked about who the new producer of World of Warcraft TCG will be, but apparently we'll know by this weekend. My lord of WoW TCG is limited, but you can get more about TCG and wow gold information from our site!
General speaking, knowing more wow lord, getting more wow rewards. Some players have abilities to gather wow gold for sale, just because they know how to use wow knowledge better. As I mentioned in an earlier post, the popular concensus seems to be that Wizards of the Coast, the producers of Magic: The Gathering and D&D, would get the contract. Since the Wrathgate and Icecrown expansions will be released on schedule the release of the in-game mounts Blazing Hippogryph and Wooly White Rhino should be unaffected. These will be the new reward mounts that are redeemed in game from TCG card codes.
