The question is, did Dr K jump or was he pushed?
Since no replacement has been announced, and he does not seem to be going anywhere in particular, it may be that he was unhappy with some significant aspect of Sierra's R&D plans.
Perhaps he felt it was time, and past time, to proceed with development of SRA737.
If that is the explanation, it is not good news for SAR.
