I don't see the "10 nights credit" bullet any longer on that page (Marriott Rewarding Events). It used to be under the "Earned Valuable Points" section, but isn't showing there (for me at least.) But I do agree in that I don't see anywhere that the old 10 nights credit will end on Dec. 31st either (but I'm guessing it is coming given they have dropped the bullet from the main webpage.)
