Hmm, I'm trying to make sense of all of the Palace Chase posts lately... so, MountainHerc was a Nav with 50% ADSC left and was denied. I'm in a similar, but different boat...
My story: I commissioned in 2005, flew Legacy C-130s (aircraft commander), and I'm currently instructing at USAFA now.
I have a 10 year UPT ADSC that expires Nov 2017 (so I'm right on the 2/3rds bubble)... no other ADSC.
I'm betting on the Legacy going away, the fact that the AF wants to kick out 84 of us 2005 11Ms in a few months, and not being qualified in the Legacy anymore as reasons to make a nice, smooth transition to the Guard/Reserves. Sure, like Fifty-six & Two said, phasing out Legacy aircrew will not happen overnight, but I'm not even current/qualified in the Legacy and I don't belong to any AMC unit...
