Isn't that a bit simplistic though Alan. Unlike Sony, Nikon (and Canon) also have a full and current range of traditional DSLRs and FX and DX mount lenses which also had to be produced and supported alongside, and new units designed (e.g. 500mm PF, D6, D760 etc. etc.) so a company like Nikon obviously needed to be a little conservative about putting all their eggs in one basket. Afterall, if their mirrorless offerings fell flat on their face and
all of their time and R&D money went into the mirrorless system and alienated their DSLR base it would pretty much be suicide. I'm guessing from a conservative company like Nikon, it was always going to be a gradual transition into mirrorless rather then all or nothing.
Also, don't forget that at the same time they were also designing a new lens mount for the system and completely new design of lenses to fit that. Furthermore, just copying what others have already done and picking pieces of technology already available and hoping for the best doesn't always guarantee success. It would always be the case that a Nikon MILC system would have to look and most importantly feel like a Nikon (not a Sony), just like the new Canon's feel like a Canon, to ease their current user base into this area.
I stand by what I said before I feel they have done a great job with the hardware for a first iteration.
Now if we are talking about Nikon as a great communicator or as a company that understands or knows what it's customer really want...well that's a different conversation
