I do think that digital slr body/lens systems will be the norm for
mid/upper digital photography. Same as 35mm systems are today.
Digital point and shoot will, of course, be everywhere. (My
daughter has a 'Barbie' digital for god's sake!)
It's possible that EVFs will be an accepted alternative to SLR.
The advantage of EVF is that there is no reflex mirror, allowing
the design of lenses that get closer to the sensor. This is an
advantage for wide angle and normal lenses, and but not an issue
with telephoto lenses.
In the 35mm film world, it is acknolwedged that high end non-SLR
equipment provides the ultimate in sharpness. Leica and Contax G
are examples.
The interesting question is the future of 35mm film. My crystal
ball says: within 5 years, new sales of 35mm slr systems will be
approaching zero. Digital systems will be king. Existing 35mm
equipment will continue to be used because of the money invested,
but new sales? No.
My crystal ball is fuzzy.
A full frame 9 megapixel camera based on the 35mm sized format may
surpass the qualiy of 35mm film.
In 5 years, 35mm film will most certainly still be being used in
large amounts. But you may be right about the death of 35mm by
professionals and serious amateurs. 9 megapixel full frame cameras
will sway most of the sophisticated film photographers.
