Like you, Bob, I've not seen another word about AMC's demise.
I've noticed several movies here and there on TCM that used to be on AMC...but never on Turner....for ex. Charade, To Catch A Thief...so TCM must be buying off their movies. Hopefully, it's a going-out-of-business sale.
I'm optimistic and still trust Robert Osbourne when he says TCM isn't going to change their format.
