Electronic Arts confirmed today that it will acquire Angry Birds publisher Chillingo in a deal rumored to be worth just under $20 million. Unfortunately the birds aren’t likely to see much of that cash, as Rovio, the developer behind the wildly popular mobile game, is not a part of the acquisition. In fact, Rovio has since told TechCrunch that it will not be using Chillingo anymore — news that EA is likely not too happy about. Chillingo has published several popular mobile games including Angry Birds and Cut the Rope, developed by ZeptoLab. Angry Birds and Cut the Rope are currently ranked No. 1 and 3 respectively on Apple’s paid app charts. The deal comes on the heels of the company’s $400 million acquisition of Japanese mobile game developer Ngmoco. Clearly, EA has no plans of slowing its attack on the mobile gaming space.
