If they charge $14-$15, Apple will get 30% of $14-$15 and Amazon will still get 0% because they have to pay 30% to the publisher. That's even assuming their publishing deal allows them to change the selling price, which it probably doesn't.

Amazon will have to create a web app that functions as a Kindle Reader in order to let their content remain readable on iOS (and that's exactly what I'd start doing now if I were Amazon, if such an app weren't already in development).
