A report on SuperData Research has some speculative analysis about World of Warcraft revenue rates, saying they "believe" that Blizzard's MMORPG earned about $93 million in April, compared with $204 million seven months earlier. Saying this is partly due to the game's slow but steady subscriber loss, they say that it's to the point where the game needs to place greater emphasis on microtransactions, but a switch to a full free-to-play model "is currently too much of a jolt for WoW, and doesn’t make sense with the current metrics."
