I'm finishing my MA at Nebraska as we speak, just so you know where I'm coming from...
Nebraska admits a LOT more PhDs than they fund. There's always the opportunity to reapply for funding in subsequent years, but initially they take in way more PhDs than they have the money for. I've heard rumors they admitted 20 creative writing PhDs this year and only funded two (rumors, mind you, but they're not much of a stretch).
I do know people have heard about funding already. There's some bad blood going around in the building, actually, because none of the MAs who came in funded got funded for PhD.
Hope that provides some answers...good luck!
