The Digital Reader is claiming to have some inside information that Amazon (and fellow e-booksellers Barnes & Noble and Kobo) know their iPad and iPhone Kindle apps will get bounced from the App Store by Apple in June as a result of Apple's new requirements. (The requirements call for in-app subscriptions that at least match external subscription prices and content.)

Apple’s in-app system can’t handle more than 3,000 items. This means that it simply won’t be possible for any of the ebookstores to use it...At this point everyone is resigned to the fact that Apple will pull the apps come June. Amazon, B&N, and Kobo are stuck.

And yes, I have off the record confirmation that they’re going to let Apple pull the apps. What else can they do?
