Will Kindle remove the web store button, or will Apple remove Kindle?

Today, June 30, is supposedly the deadline for apps like Kindle to remove buttons or links to their external web stores or risk expulsion from Apple's iPhone and iPad App Store. Originally, Apple was requiring developers to not only remove external store links but also match any external sales and pricing with identical in-app purchase options (which would require giving Apple 30% of the price). Apple quietly stepped back from the content and price matching provisions earlier this month, but not the prohibition against external links.

So will Amazon update the Kindle app today with the Kindle Store button removed, will Apple "Sony" the Kindle app, and pull it from the App Store after the deadline expires, or will the Kindle app keep the button and stay in the store (either with Apple's permission or convenient silence)?

Apple makes and markets the competing [iBooks](http://www.imore.com/tag/ibooks] and associated iBookstore for iOS.
