An article over at Gamespot has recently brought to attention the fact that Blizzard is seeking both a manager and a director for a new unit within the company: "Microtransaction Strategy". For those of you paying attention to ongoing trends in the video game industry, this in particular might pique your interest. As we all well know, 2013 was a landmark year in terms of new titles for Blizzard with Hearthstone: Heroes of Warcraft, and their announced MOBA, Heroes of the Storm. Both of these games are going to be free-to-play, which means that they'll be relying on microtransactions to generate cash flow.
With World of Warcraft being one of the few remaining MMOs that still charges a monthly subscription fee, I think it's fair to say that Blizzard hasn't been at the forefront of microtransaction-driven financing, despite the existence (and success) of WoW's purchasable pets, mounts, and transmog gear. However, the establishment of both the Microtransaction Strategy team and job openings therein point to some development along that front. It will be interesting to see what other types of microtransaction offers become available in Blizzard games in the future.
