There was already some news with the WoW Card Game where Blizzard announced that the license would not be renewed with Upperdeck. Some players who collected and played these cards were waiting to see which way this would take because there was even talk that the game could be taken to the computer. Although, for now, those answers will remain unknown, Blizzard has added a new section of the card game to the official American forums, Just to talk about the card game.
As he said Drazthal, Blizzard is not going to leave the game, much less to its players. Personally, I hope that the game will have much more promotion in Europe than it has had so far, with adapted support and infrastructure. I know many people who love card games of this type but it is difficult to know where to start.
However, it is good to know that Blizzard has not forgotten the subject and let's wait to see where all this comes out. Presumably this section will appear in the not too distant future in the official European forums.
Edito: The Card Game forum in Spanish forums.
