There is no number to tell you and it'll be fruitless to put together our own numbers.
>My user group is getting restless
What are the concerns at all?
Are we talking about your application users or a group of VFP users/developers. Are they restless to get/use new technologies? Or are they restless because they fear the end of the world?
Just a short statement by me, too:
VFP is discontinued, that's well known for 7 years nor, it continues to work anyway. To use new features of Windows, Office, UI, you need to use new languages and .NET Framework (on windows), if you would need to target other OSes you'd need other languages anyway, even not .NET, the most common denominator still is HTML,CSS and Javascript plus some DB, nosql or sql, webservices.
But the gap of what you can't do with VFP and need to have is not very large, is it? It may never get large for business line applications, as we still do our rather simple data entry forms. The other important part, data processing, is part of a database server, it can be moved to the database and doesn't need VFP improvements. You can make use of MS SQL Server or other database server improvements 100%. The other interesting development is offering parts of functionalities on mobile devices, some info for management, some data entry in labs or stock or for working mobile all in all, and for that you also don't need complicated apps, but perhaps new ways of data entry by camera, OCR, barcode, and all of that is mainly built into the devices, we just can use it.
What's lost is to do everything with one language and platform, get used to that.
Bye, Olaf.
