Where do Brian Roberts and Steve Burke stand on “The Jay Leno Show”? That’s just one of the many “burning questions” still unanswered now that the Comcast deal for NBC Universal is finally done, Variety reports.

And “Will Comcast be forced to divest any stations in order to secure regulatory approval?”
