>That sure sounds like an interesting formula. Is there some other product that gets credited when someone purchases a VFP upgrade directly, or is it that VFP is getting a big piece of every MSDN Subscription? In any case, it sounds as though VFP is sitting pretty from what you say, with no need for any marketing effort whatsoever. Just sit back and take a piece of every one of those MSDN Subscription sales, regardless of where they come from. A curious situation indeed!

The percentage is simply based on the percentage MSDN subscriptions obtained by people who use VFP as their primary development tool. Most FoxPro developers have yet to upgrade beyond VFP 6.0, so there is lots of marketing needed and will continue towards the FoxPro community.
