This is my take on this and my personal opinion. Mirrorless cameras are the future not only because of their superior technologies but also because they tend to be small and practical, especially for travelling. Shutter count has been discussed but it has also been discussed that it bears little when considering the wear of the camera. Modern shutters can take at least 150,000 actuations without issues. The better cameras can double that figure. Nobody can deny that a large group of professional photographers have adopted mirrorless.

Mirrorless wear like any other camera, they do not last forever but surely many of them will outlive us. The recent discussions about Nikon and Canon abandoning the research and production of new dSLR cameras tell me a lot. I do not know about other places but most recently in Japan a mirrorless camera, the Olympus EM-10 Mk II was the camera that most Japanese favored. It is a solid fact that mirrorless cameras are selling far better than dSLR bodies and that new mirrorless cameras are better than ever.

I do not believe the dSLR will disappear forever since there will be ample supplies of used models and manufacturers will be keeping parts and servicing these cameras. What could happen is that eventually and, at the present trend, there will be a better market for mirrorless and less for dSLR cameras.
