I think the start of the service was originally scheduled for June or July and it's been pushed back a couple of times. Once a week to a station they otherwise don't serve doesn't sound like a strong committment - I suppose OW will do "something" if you book and purchase an xONEx that begins MRU-JNB and then the service disappears...
