It's a D850, not D820, and the touch screens appeared before - although not in high-end DSLRs. Sony is not so shy to use this approved tech since a while. Nikon is one of the most conservative manufacturers.
As for the backlit sensors: I don't know, but 858 mm<sup>2</sup> is a challenge to make and pack 53.263 pixels on each mm<sup>2</sup> (sometimes I exercise my calculator ^_^ )
If one bought a camera before digital, there was already a choice to fumble in 135 or 120 rolls or get a 126 or 110 pack and just ram it in a camera like a tape cassette. Lateron APS films offered a bit more comfort, but basically professional cameras were much more expensive than they are these days - concerning the annual salaries.
