Even you must admit that the language used in those communications was specifically chosen to imply that once that signature was gained that the deal would be done.
What "significant progress" could have been made with respect to finalizing the deal that just required a signature, unless there was more that needed to be done afterwards that wasn't addressed?
I'm just saying that we're missing something that I believe should have been made public much more clearly, based on what they felt they WERE able to say and that apparently not being the complete truth.
