The only thing I have heard with any type of consistency is that the IAM has said they are not willing to discuss additional concessions. Beyond that everything is rumor, speculation and opinion. I would prefer not to add to the rumor mill, but get the facts from anyone in the know..
I hear their official stance is you will be told what you need to know, when you need to know and we know what you need and what is best for you. So there should be no questions and we do not need your input.
