SQL CE is no longer under active development. Most Microsoft tools that need an embedded engine use ESE(Jet Blue), which is bundled with Windows. For third-party desktop developers, the replacement is SQL Express LocalDB. For WinRT developers, Microsoft has paid the SQLite developers to port it over, so that it passes Store validation. Windows Phone still uses SQL CE, but the only interface to it is LINQ-to-SQL. So Microsoft could conceivably swap out the backend at any time.
