Harold Ryan is leaving as the President of Bungie after a run of 15 years with the development studio. Coming in to take over as President is the former COO, Pete Parsons.
"I want to personally thank Harold for his friendship, passion, hard work, and dedication in helping make Bungie the great company it is today. As a team, we celebrated many victories and weathered many storms," said Parsons.

"To the players of Destiny, I want you to know that my number one priority, and Bungie's, is and always has been to deliver great games that we can all share together. I believe that Destiny is a one-of-a-kind experience. I also believe you have yet to see our studio's best work. My new role here at the studio will be entirely focused on fulfilling that promise."

Harold Ryan did not make any public statement about his departure.
