Nikon was looking for a home run. The last home run came with the SLR which changed the camera industry and is still dominate - independent of digital sensor or film. Home runs are difficult to come by. What people want is not important - it is what people buy is. I expect the Nikon 1 type cameras will be around in the mix for a long time. However, just as the flexibility of the SLR system limited the rangefinder cameras of the 50's and 60's to a niche - I expect the flexibility of the DSLR system will limit the mirrorless to a niche. That doesn't mean that the companies won't pursue their development or limit their utility.
