Well, as was already pointed out, the name of the game is called Hearthstone: Heroes of Warcraft. So, just adding a card directly from another game, like a Tyrael legendary, will probably never happen. They may however bring in gimmicky crossover cards; something like Grunty (the murloc marine non-combat pet in WoW) or something along those lines.
