We knew it. You knew it. Even your dog knew it and now CBS is said to finally have a plan in place to say farewell to Katie Couric at 'CBS Evening News.' Sources familiar with the exit strategy tell The New York Times that a major announcement will be made when Couric returns from covering the royal wedding of Prince William and Kate Middleton.

What will they say? According to four insiders who spoke on the condition of anonymity, CBS will announce in early May that her successor at the 'Evening News' will be '60 Minutes' correspondent Scott Pelley.
