Thre's only one version, VFP 7.0 profesional, AFAIK. Where do you hear about Enterprise edition?

>We are, finally, going to purchase VFP 7.0 and are trying to figure out what the difference is between the Professional and Enterprise edition. Can anyone fill us in or point us in the right direction. We are not going to be purchasing this as part of the MSDN subscription or anything, just straight VFP.
