Slight mistake. The list will need to hit 7200. Currently at ~ 3600. With the published plan between now and 2020, expect around 350ish upgrades. Anyone with a post 2011 DOH can expect at least 6 years from now to upgrade. New joiner today would be 12 plus years. I for one am happy for this. After 20 years in the lines with only a brief command prior to 9-11, I'm sick of babysitting cocky douchebags who sit left of me only because of their lucky timing. Plenty of briefing talking gods who couldn't hand fly their way out of quife.
