For those who are more advance in age, might remember the excitment of manual SLR technologies. Then came the autofocus, then the compact, and then the bulky digital back with very much SLR front.
Today we see what i would call mini-DSLR with quality and functions surpassing early DSLR models.
Looking down the road, it won't be long when 99.99% of photographers would not have the need to use heavy and bulky DLSR when small, light and cheap new models can offer same performance.
Question would then be, how high a resolution will the mass consumer market grab for? Many of us today could be holding a 12Mp specification but set at lower level, 5mp seems to be common.
I see the end of full size DSLR in the real near future. Delay not by users, but the makers themselves to keep their production lines / parts / dealers breathing.
