There's also the point that most big time producers and publishers want a known quantity. They want to minimize risk, so they continue with the sequels or with the writers who they know aren't writing their best anymore, but who will sell based on name recognition alone. New writers, or developers and artists that want to do something different have to do things on their own.

Look at the top of the fiction best seller list -- you're going to see the same names over and over again from year to year. That means that the public buys from people they know and the publishers continue to publish the same known quantity. That certainly doesn't mean that those 10 people are the only people in the world who know how to write. There are plenty of talented writers toiling away on their own taking risks that the established publishers aren't willing to take.
