Following the forthcoming release of a deck game by Blizzard named Hearthstone, people started wondering whether it would be possible to implement it in the actual World of Warcraft game itself.
The latest Patch 5.4 Build has revealed an interesting deck board added to the game files. That made people ask about the implementation on the official forums.
NO PLANS TO IMPLEMENT HEARTHSTONE IN WOW
This thread, has an official "blues response" clearly stating that: "There are no plans at the moment to implement the game within WoW, even though the developers had been considering it."
BLIZZARD CAREFULLY TESTING MICROTRANSACTIONS
It's safe to assume that with the introduction of an in-game World of Warcraft store in Patch 5.4 along with the launch of Hearthstone, where you'll be able to purchase decks, Blizzard is carefully testing microtransactions, because they want to see how players will react to it, before offering World of Warcraft Pay to Win services in the game store.
HEARTHSTONE SUPPORTED PLATFORMS
This new game will be available on several platforms, starting with Mac OSX/Windows. The iPad version will be available for iOS devices upon launch too. Android platform will not be supported from the beginning.
