Gamasutra has news that former Rift producer Scott Hartsman has returned to Trion Worlds where he will take over as CEO of the developer. Word is: "Outgoing CEO and Trion Worlds co-founder Lars Buttler remains attached to the studio as a member of the board, a Trion representative was able to confirm for Gamasutra. However, his new role has not yet been defined." This was followed almost immediately with word that Trion is closing its San Diego offices. Here's word: "We can confirm that the San Diego studio will be closing. The day to day operations of Defiance will be moved to our Redwood City studio where it can be managed alongside Rift and our other in development titles including ArcheAge and End of Nations. As part of this transition, we are working hard to ensure that a number of great people will be making the move from San Diego to the Bay Area and continue their work at Trion."
