Sony Computer Entertainment announces the resignation of Phil Harrison, who had served as Worldwide Studios president. The resignation takes effect at the end of this month, at which time Kazuo Hirai, President and Group CEO of SCEI, will assume Harrison's responsibilities. "Resigned" is often code for "fired," but the announcement doesn't include the 'spending more time with his family' code, so this may be a genuine resignation (GamesIndustry.biz is reporting there are indications Harrison may be joining Atari). Either way, the reasons behind the move are not apparent from the press release:

Tokyo, February 25, 2008 – Sony Computer Entertainment Inc. (SCEI) today announced that Phil Harrison, President of Sony Computer Entertainment Worldwide Studios (SCE WWS), will resign from Sony Computer Entertainment Group as of February 29, 2008. Kazuo Hirai, President and Group CEO of SCEI, will immediately assume responsibilities as president of SCE WWS, in addition to his current duties.

Prior to the launch of the original PlayStation, Phil Harrison joined Sony Electronics Publishing, Ltd. in 1992, which later evolved into Sony computer Entertainment Europe, and since then, he has made a tremendous contribution to the company playing a strategic role in the launch of four PlayStation platforms, as well as building strong relationships with game developers and publishers throughout the world. Since his appointment to the position of president, SCE WWS, Harrison applied his considerable skill, knowledge and expertise to lead SCE Group’s first party game development as well as aggressively pursuing the development of new online entertainment experiences.

“As one of the founding members of SCE, Phil played a key role in the development and growth of the PlayStation business and our industry,” said Kazuo Hirai. “It is sad to see him departing from SCE, but I wish to express my gratitude for his many invaluable contributions and also wish Phil the very best of luck in his future endeavors.”

“The past 15 years at Sony Computer Entertainment has been the defining journey of my life so far,” said Phil Harrison. “I am grateful to all the PlayStation family for their incredible support, guidance and friendship. It has been a privilege to serve as part of the team and be inspired by them on a daily basis. I am so proud of everything PlayStation has achieved and will continue to support its future in every way I can.”
