No, I have none, so I cannot upgrade, alas.

I could buy yours and upgrade it, but it would cost me $299 plus whatever you charge, so in that sense I could (also) look for A7 Com and then upgrade that for $149 instead...

If you do not sell it, however, I can certainly keep it in mind in case nothing else comes along. It is less than a new A7 licence anyway, so thank you for that offer even if I am hesitant to accept it at this time.
