New Electronic Arts CEO Andrew Wilson has made his first management changes for the massive video game publisher since he was named top boss last week.

The changes are outlined in a memo that EA just distributed to employees. The memo was shared with GamesBeat via a source who asked for anonymity. Some of those details leaked out earlier today, but not all of them. The memo leaves some questions unanswered for now. The memo does not point out what title any particular executive has, but it does describe what their responsibilities will be. They will effectively all report directly to Wilson, which suggests, but does not explicitly spell out, that the chief operating officer role no longer exists. So far, we know of no major executive departures.

Patrick Söderlund, currently the executive vice president of the EA Games development studios, will continue in that role and also add Wilson’s old title as head of EA Sports. Meanwhile, Frank Gibeau, the president of the EA Games Label (EA Games, EA Sports, Maxis, and BioWare) will now run EA’s mobile division. The memo does not say whether Gibeau will continue to lead the EA Games Label.

Peter Moore will continue to lead Global Publishing and Marketing organizations as well as EA’s Worldwide Customer Experience and Global Media Solutions teams. But the memo does not say if Moore is still chief operating officer.

Lucy Bradshaw will continue as head of Maxis, the maker of The Sims and SimCity games, but she will now report directly to Wilson. Rajat Taneja continues to run the technology platform, Blake Jorgensen leads finance, and Gabrielle Toledano leads human resources.

The announcement was made during a company-wide “town hall” meeting today and detailed in the memo below.

The choice of Wilson as CEO (replacing John Riccitiello, who left the big game publisher in March) was a surprise to many. He leaped ahead of candidates such as Gibeau, who has been at the company for more than two decades, and Moore, who was previously the No. 2 executive. Both Gibeau and Moore may have been too closely identified with the leadership of Riccitiello, who resigned after the company missed expectations. They both appear to be staying on board, for now.
