Forest Whitaker set to star in Criminal Minds spinoff

Oscar winner Forest Whitaker (The Last King of Scotland) is in final negotiations to star in the Criminal Minds spin-off, as per TVGuide. The new cast will be introduced this spring on the original CM, and I'm assuming it will take twice as long since it will have double the cast to explain the profile one at a time. Has anyone noticed that as well? I enjoy the show, but that is the only thing I can never get over.
