This business of the waypoints being programmed into the FMS prior to the last ATC call is unofficial. It's a leak to the media from some unknown source, so I would discount it until it is confirmed. So many of these leaks have turned out to be a crock.

The media are like an echo chamber, repeating the same speculation over and over until they start to hear their own speculation reported by other media outlets, then they take it as fact.

I was watching Captain Les Abend on CNN earlier. He was quite measured and sensible in his comments. Definitely one of the better commentators.
