John Wagger writes: One of the world's largest gaming publishers and developers Electronic Arts has quietly put itself up for sale. While there have already been talks with private equity companies, the talks have not resulted in anything concrete. One of the sources is saying that EA would do the deal for $20 per share (currently at $14.02). Over the past year EA's stock price has fallen 37 percent. Like other major game publishers EA has been struggling against growing trend of social and mobile gaming.
