IGN reports that 343 Industries Senior Art Director Kenneth Scott has stepped down from his position and assumed a position of Visual Design Consultant as he'll continue to work with the studio remotely.
The reason stated is that he wants to spend more time with his family as his wife Corinne Yu recently switched jobs from 343 Industries in Washington to Naughty Dog in California. Replacing Scott is his longtime colleague Nicolas "Sparth" Bouvier. The next Halo (Halo 5) is scheduled for release later in the year on Xbox One.
