Developer Bungie announced today that studio president Harold Ryan would be stepping down, and Pete Parsons had been appointed CEO. Parsons shared a few words about these changes on Bungie’s website:

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.
 
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. 
Bungie promises this restructuring is a new beginning, and reaffirmed their commitment to supporting Destiny with new “great experiences” in the future. What these experiences will be has yet to be seen, but Bungie continues to remain active in their post-release support of Destiny with the next big update planned for Valentine’s Day.
