No actual stats, but there is still a significant number of 20,000 hr ships in the GOM. The average age is certainly decreasing, and in 5 years it should be much better than it is now. It seems the main reason for the old models being still there is the inability of the manufacturers to turn out new equipment quickly enough. Every operator I know of is buying new equipment and getting rid of the really old stuff as replacements become available. The oil companies are making more profits than they can spend, and are throwing money around like never before, so now is the time to get new equipment.
