I think that a hereditary DSLR AF optical path’s method will be rewrote, a hereditary way is a sub-mirror added to a master-mirror’s backside, that is source from the Pentax’s patent (registered in 1973-1979), Pentax ME-AF was a first applied example, in 1980. Today’s a master-mirror way still is a faraway origin from the Pentax’s patent in 1956.

cancels a sub-mirror would win the many advancement, and DSLR’s cost would obtain reduced, reducing the number of parts, reducing the adjustment items at the production process, the optical path in AF-error would obviously be improved.
