Chicago is not even close to a top dog in crime in Chicago but they still have anywhere from 28-50 made members so there still there just not in the traditional sense and how long they will be there is anyones guess but the gangs will never get into loansharking,gambling,unions,or construction bid rigging so they still have there place. Also the Colombos along with the other 4 families in new york will be the last to go so the colombos will be around for awhile and the new generation some are into steriods and drugs but out of the new generation they will still find guys that can make money and not rat although the number of guys of that caliber is and continues to get smaller
Since the gangs won't get into that stuff, that's why the outfit or whatever it is now will always be around. As long as there is people that want to gamble, people that need loans and unions, there will be organized crime in Chicago.
