From my understanding MOND has some pretty big hurdles to overcome as a model. When speaking to my PHD friend he still feels it's hammering away at a model to further fit observations; it might prove useful but is certainly no smoking gun for us to wave a flag that we're onto something. It's a 40 year old concept that hasn't born much fruit yet.

maybe there is a modicum of progress?
