I didnt see it publicly anywhere. It seems to be their response to 'awkward' customers like me who ask about it explicitly. I know about at least one more person (I think it was Richard-craftycurate) . That got offered this deal.
If you upgraded to v7complete you immediately and forever lost your upgrade privileges. If you decide you want to move to v7 infinite anyhow they will give you a voucher worth $400 towards the purchase of a new (not upgrade) v7inf. So instead of paying the full $900 for v7inf you will pay 'only'
$500.  As I said if you add the $100 you already paid for the complete version of v7 moving up v6->v7 will cost you $600 rather than $400 that anyone else paid to move up to v7inf directly.
This seems way over the top to me. I can accept their 'restocking' fee of $15 if you return complete, I can even accept double that, but an extra $200... it is not a serious offer.

(and the fact they dont  say that this is their general arrangement in any official list/publication, also seems...well, underhanded?)

EDIT: I didnt see your latest post while I was writing this one.  I dont want to purchase another version of v7. I only need ONE, I only asked for one.When you upgrade any of the other stages in the artist line they dont tell you to keep the version you have and pay for a completely new one (even with discount). Why should not  the same policy apply to the complete-> infinite switch?
That was my original question, and it still is.
