Hi Arcady,
As far as I know, SQL Anywhere is alive and well. In addition to being offered as an product for sale to end users and OEMs, it is part of, or included with, many other SAP solutions. For example, SQL Anywhere is included as part of Business Objects and the SAP Mobile Platform, and SQL Anywhere data synchronization (MobiLink) is currently in beta as a new offering for the Hana Cloud Platform.
There is a recent product roadmap for SQL Anywhere posted on SAP Service Marketplace, which you should be able to access if you have an account.
Development is continuing on SQL Anywhere and a new release is planned for this year (I don't believe a firm date has been announced yet).
Hopefully this information helps to address your concerns. If not, please feel free to contact me directly if you have any further questions about the future of SQL Anywhere (firstname dot lastname at sap dot com).
