Well I got the fellowship last year and so far have been flat-out rejected from two schools and not invited for interviews at two others. I have two left to hear from I'm still hoping that they've just skipped inviting me altogether and will just admit me but I doubt that's the case!
Just got rejected from Stanford Ecology/Evolution with an MS and virgin NSF GRF in hand. Admissions are like nature, red in tooth and claw. Such is life, I suppose.
