This is the most current word I can find. It was in a thread where a Sync Framework 2.1 user found a bug and asks if SF is sundowned and replaced by SQL Azure Data Sync... The incremental release sounds like bug fixes and nothing more. What is the plan for sync, %100 cloud?
Update. This hot fix has been released. The following support page provides detailed information and hotfix download.
Microsoft stays committed to serve Sync Framework application developers' needs. We're currently planning an incremental release in the next 6-9 month timeframe. If you have any specific feature requests, we're here to listen.
