This is something I'm also looking to do in upgrading to a retina mini 32GB. There really isn't a fixed price Apple drops the refurbs too like they do when they drop previous-generation products down $100. I wish they would, as it would be easier to gauge. Right now the retina mini discounts are $60-130 off retail depending on the configuration. My best guess is that these will stay the same, but be reflected off the new retina mini retail price.
