John Riccitiello is stepping down from his post as EA CEO effective March 30th, reports Polygon, saying he will be replaced on an interim day-to-day basis by Riccitiello's predecessor Larry Probst as they hunt for a permanent replacement. They have a copy of his resignation letter to the board, which suggests by its tone was requested. "This is a tough decision, but it all comes down to accountability," Riccitiello resignation letter reads. "The progress EA has made on transitioning to digital games and services is something I'm extremely proud of. However, it currently looks like we will come in at the low end of, or slightly below, the financial guidance we issued in January, and we have fallen short of the internal operating plan we set one year ago. EA's shareholders and employees expect better and I am accountable for the miss."
