Farmville title. Writer Alex Harvey, while listing out his work for "communications agency" Isobar, says he participated in the "successful" pitch for Farmville 2. That tells us that Farmville 2 was at one point a suggested thing, and that Zynga has said yes to it becoming a real thing.
For now, that's all we know. It's probably fair to say, however, that there will be cows, and you will click them.
Update: We reached out to Zynga to ask if there was any news on this front, but the company declined to comment on "rumors and speculation." Fair enough.
