>>The VFP7 team has only one requirement to MS, that is to show that the product makes more money than it costs. Right now it does, if in the future it fails to make money then it will disappear.

>Just curious if you know, but how does MS have accurate figures if VC, VB, and VFP are all sold on the same Discs?

On method might be comparative projections of ratios between the products based on registrations, logins on newsgroups, attendance at seminars, surveys, statistics published by trade magazines based on *their* surveys, etc, etc.

You could average out several such comparisons, weighting them according to known disparities, ignoring some that are clearly out of balance (UT Fox vs UT VB for example), and come up with some fairly accurate estimates.
