Given the attraction for the mini, no reasonable price for the mini 2 with retina and keeping the size and weight acceptable will be turned down.
Wow, you've never been to a marketing class have you? Do you think they would have sold as many if the price was double? Do you think the average buyer knows the difference between retina and non retina? Clearly you're thinking of yourself as a buyer. I am the same way, *I* would pay twice the price for a retina display... wait NO I WOULD NOT! See, between you and me Apple's already lost a buyer at a 100% price increase.
