We have no way of knowing until the a/c is found.
To my knowledge ACARS does not transmit changes in the FMS to anyone. I am not even sure if that info can be pinged from the aircraft and I am thinking not.
The info "may" be retrievable from NV-RAM in the FMS once the ship is located.
I don't consider the water between Malaysia and Vietnam "open ocean" either. I have flown between KL and HKG many times which is the approximate route and you are in radar most of the way.
JJ21...you are either new or making stuff up.
