I may be wrong, but it is not my interpretation that the major upgrades will be free to Mac App Store customers ...

(It doesn't look like a sustainable business model, for a start ...)

As I understand it, it is simply that the minor (free) upgrades will be handled automatically by the MAS system. Even if you buy through the MAS (and thereby burden yourself with the variant bundle identifier) you will still have to pay for the major upgrades ...

You will also be excluded from the betas ...

(I have to smile at this acronym because MAS/maas/amasi is a fermented milk drink in South Africa ...)
