So since the announcement of the new iPad mini retina, only the 16GB original mini is available, and not in higher capacities. I have a 32GB mini and the light sensor seems to be no longer functioning. I did tech support with Apple and determined it wasn't software and to take it to a Genius. When I finally get around to going to the Apple store (not sure when I can, and I still have 6 months left on my built-in Applecare), what do they typically do if they no longer sell that model (and also assuming that refurb warranty backstock has been depleted) and yours needs to be replaced? Do they give you a credit, or do they typically just give you one of the newer gen to replace it?
