Sony has announced that Jack Tretton will step down as president and CEO of Sony Computer Entertainment America as of March 31.

The company said his exit was “a mutual agreement” between Tretton and SCEA not to renew his contract, without providing additional details. In a statement, the 19-year veteran of the company said, “Although I will deeply miss the talented team at SCEA and the passion demonstrated every day by our fans, I’m very excited about starting the next chapter of my career.”

Tretton has been with SCEA since its inception in 1995, and played a pivotal role in launching the original PlayStation and subsequent iterations, including the debut of the PlayStation 4 last fall.

Shawn Layden, currently exec VP and COO of Sony Network Entertainment International, will become president and CEO of SCEA.

Sony said it has sold more than 6 million PlayStation 4 consoles worldwide as of March 2. The PS4 went on sale on in North America on Nov. 15.
