HALO 4 Creative Director Leaves Project

Ryan Payton, the creative director for Halo 4 has left the project, citing creative differences with the direction of the project. As creative director he was in charge of "developing the game's story and overseeing the creative team who were planning the next trilogy of Halo games". He was quoted as saying that he was not leaving because the game is in bad shape:

"The Halo I wanted to build was fundamentally different and I don't think I had built enough credibility to see such a crazy endeavor through. I think time is the most valuable thing we have, and I've decided that I'm not going to waste one more day working on something that doesn't speak to my values."

Not to mention that Halo 4 was actually headed in a different direction than what the guy in charge wanted which to us makes it look like Halo 4 may not have a clear developmental direction. After this are you worried that 343 Industries will not be able to handle creating the Halo 4?
