Apple deleting developer’s iCloud libraries in advance of iTunes Match launch

After Apple teased us by purging iTunes Match beta accounts, only to make the service available for developers again, it looks like the wait for iTunes Match might finally be over (for the last time). Indeed, Apple has just sent out an announcement alerting developers that all the music they've stored on iCloud will be deleted Saturday, November 12th at 10:00 AM PT, in preparation for the big launch. In addition, Apple is instructing users to turn off iTunes Match on your computer and all iOS devices, including Apple TV. Sure, it's no longer October, but we'll take it!
