Until the new T&Cs are released nobody will know what they state, which will hopefully be by the 18th. You are entitled to your guess, and your guess may prove correct, but we should wait for facts before proclaiming there is a change. There is a difference between thinking there will be a change and there actually being a change.

I have long advocated conducting any meetings needed for the nights credit before the new program starts to be on the safe side should the rules change, but again, that is a far cry from knowing there is a change. The rumor started because a blogger said he knew someone at Marriott who said there will be a change, and suddenly many started pointing to that statement about nights getting Silver status with one meeting as being new and a clue, but nobody remembers who the blogger was, the post can no longer be found and bloggers have been notoriously wrong through the past three months.

But to the immediate point, what is linked by the OP has been out there for months. It is not new.
