The disk problems with the A9home would appear to be more do with some errant sotware rather than any actual problem with the OS. Many people do not have disk issues
I do however very much agree with you on silence aspect. AD6 should release an official statement advising users what the current state of play is with the OS development. Even if they are unable to give an exact date that RO6 will be release they could at least say they were hoping to make it available last quarter 07/1st quarter of 08.
