I doubt there is anything to this technology, considering Rossi could not get a customer to buy it. But in the unlikely event there is something to it, I would have to disagree with you that: "the original source of this very peculiar provisional is the convicted and compulsive condominium buyer AR". From what I understand, Piantelli, and maybe Focardi would get the credit.
I am sure IH is maintaining the provisional "just in case". The minimal cost to keep it active is cheap insurance.
