Apple has sent an email to developers notifying them that their iCloud libraries housing iTunes Match data will be wiped on Monday, September 26th at 9AM PDT. The reason for the wipe is to "improve the overall quality and reliability" of the service. The news comes after Apple wiped all the iCloud backup data on Thursday, September 22nd.
We believe these are preparations for Apple to launch the final Golden Master (GM) version of iOS 5. Apple had been planning to declare iOS 5 as GM on Friday, September 23rd, though we haven't heard confirmation yet if that had actually taken place. Also on schedule was to start installing iOS 5 GM onto new devices in their factories on Monday, September 26th. Assuming all this has remained on schedule, we expect the final GM version of iOS 5 to be release to developers as early as next week.
iCloud and iTunes Match services have been running in developer beta for the last couple of months. The public release is scheduled for "Fall", and it seems likely Apple will announce the ship date at their rumored October 4th media event.

The developer program is just that...a program for developers. I almost wish there was a requirement to prove you are actively developing for the platform to keep your membership.
This is a private beta as very distinct from a public beta.
The deletion is to avoid problems in the future, as some of the data stores might have changed during the beta development.
The issue is that the vast majority are using the program as part of a "buy your UDID a copy of iOS5". None of those people actively report bugs, they just complain and submit negative app reviews.
Quite the rant, but this is very different. This is a brand new feature that they were very clear would be deleted near the end of the beta. Same thing with device backups on iCloud. it wasn't a surprise to anyone as they were telling devs from day one that stuff would be deleted as time went on.
I'm with you, I have lost stuff with MobileMe, too. Just be sure to judge appropriately.
