Apparently you have not been following the
News on the ISO 13485 revision - 2011 - 2012 (now 2014?) thread. One of the ISO 13495 resident experts and member of the ISO TC 210 has already mentioned that the upcoming version of the ISO 13485 standard will NOT follow the High Level Structure, thus, by definition, will not be aligned with ISO 9001:2015. How compatible will ISO 13485:2014 and ISO 9001:2015 be? Impossible to answer at this time, but it seems that they will significantly diverge from the current "alignment".
Similarly, a couple of people have already mentioned in this Forum that the ISO/TS 16949 standard is NOT going to remain aligned with ISO 9001. While that is unsubstantiated, at this time, there is a chance that several standards, currently using ISO 9001 as the baseline, stop doing so.
