How about giving owners of VFP7 a 100% credit (of what they spent on VFP7) toward the cost of an MSDN subscription? That way, the VFP developer would feel like they made their loyalty to VFP clear.

>We want people to upgrade to VFP, and we are promoting VFP via MSDN Subscrptions and will continue to do so. VFP works great with VS .NET, more and more VFP developers are using ASP.NET with VFP for example. MSDN Subscriptions is a great value for obtaining products and tools beyond VFP only.
