Re: IOS 7 Dummy Question Thread
The answer is, simply put, "we don’t know". The Apple App Store does not have the ability for "upgrade pricing", so developers are left with 2 options: (1) continue supporting/enhancing/tweaking the existing app and offer free upgrades to all users who have previously purchased the app; or (2) scrap the old app, rewrite it with a new name (myApp becomes myApp2, for example), and users then have the choice of upgrading (purchasing as new) the new app or not. So it’s up to the developer how he chooses to proceed, and the answer to your original question is "we don’t know".
