Great article, about one my favorite areas in this field. I recalled another article I read where some Intel executive stated that future versions of what would be Xeon Phi were going to be based on Atom cores and I found one in The Register from 2011 where Justin Rattner does address this issue: "But in the future, MIC will be based on Atom cores, and then the integer gap between Xeon and MIC will start to close." http://www.theregister.co.uk/2011/09/15/intel_rattner_mic_coprocessor/

So going by this and by what you said about Bonnell not having been productized (I don't know if research silicon maybe has been fabbed though) on 22nm or 14nm, presumably upcoming Xeon Phi generations have been developed in parallel with and in connection to development on the future Atom cores (i.e. not Bonnell) and the KNC cores cores will be based on them, but as in the case of the P54C derivative extended with a 512-bit vector unit and other adaptations.
