I don't know if it is wishful thinking or a genuine belief by some when they say "decision reversed" about the MRA4 but I have heard it a bit in the last few days.
It's very sad and incredibly difficult for all those involved but the decision will NOT be reversed.
The decision that they came to has been thought over for months and they will have heard all the top level arguments for keeping it from some very articulate, intelligent and respected people.
They chose to ignore that advice and we are where we are.
