If I had to guess, they’re going to kill open scripting interfaces entirely in favor of some sort of Automator thingee: instead of publishing an AppleScript dictionary for your app, you’d publish Automator actions. One assumes Apple has either decided regular people don’t script things or scripting applications is a gateway drug to security hell, and with rising marketshare they can’t afford the risk.

The other alternative is they’re going to simply replace the OSA entirely, and they haven’t let on how that’s going to work; but they’ve decided pulling the bandaid off is the best solution, hence the rather sudden “no more scripting if you want to sell through the App Store”.
