A colleague asked me how long VFP 9 will be available for purchase, either directly from Microsoft or from other vendors, after 'mainstream supports and after 'extended support' ends. Obviously I have my own copy, but my colleague and I need to be able to tell new clients what their options are with respect to purchasing VFP, now, and in the future.

I haven't been able to determine this from Microsoft's published material. (or here).
