I agree. But in talking about the future, we have to acknowledge that DSLRs are older technology. Replacing the optical system with electronics is inevitable. It will also be cheaper. Maybe not now, but certainly in a few years. It will also be better. Some people want to believe that DSLRs should always remain, and that’s just not going to happen.
The market will decide what happens. That said, I agree that over a long enough time scale EVFs will likely replace OVFs. I just get annoyed at the gleeful proclamations that "the DSLR is dead!" and baseless product line predictions based on same.
And I hope that the SLR form factor remains because holding big glass with most mirrorless bodies is a literal pain.
