Diablo III Art Director Leaves Blizzard

Kotaku has confirmation from Blizzard Entertainment that Diablo III art director Brian Morrisroe has left the company.
Regarding Brian, he recently resigned to form a startup technology company (outside the game industry), which is why we've posted about the open position. This change won't impact the game.we're really pleased with the look and feel that Brian helped create for Diablo III, and the new person we bring onboard will work with the other artists on the team to maintain the art style moving forward.
Even though I doubt the art style will be significantly changed, it's highly doubtful the departure of the art director won't impact the game somehow. MTV Multiplayer adds a quote from their interview with lead designer Jay Wilson to highlight how important Brian Morrisroe was.
(If you want to blame anyone for the rainbows, you'd blame our art director Brian [Morrisroe]. Because Brian is more the person who drove the art style into where it is. But it didn't really come directly from him. What he brought to the art team was concepts and ideas the idea of contrast, the idea of using color more, the idea of going for a more stylized look. Because what we were looking at before was more photo-realistic. Really trying to get something that looks like a painting that was his goal. But the actual result of that came from the art team. And a lot of the environment guys, and some of the texture artists, they've all kind of chipped in to try and get the feel of something that was very unique.)
