Using the wrong metric

Back in the 80s I knew a guy with a cellphone the size of a briefcase. I told them I'd consider buying one when they could fit in your pocket. "They can't get any smaller - they need too much battery power" he told me. 5 years later I bought one that fit in my pocket.

The reason electronics get cheaper is they get smaller.  The cost for integrated circuits depends on size, not complexity.  5 years ago, if you wanted a 30+ MP camera it would have cost upwards of $20k. Now it's $2.2k.    5 years ago, it was a 44x33 sensor while today it's a 24x36mm or smaller sensor.

As I said, medium format sensor backs have been around for quite a long time.  And in the last 5 years or so, the prices have decreased very slowly.  It's also very telling that sensor sizes are not going up - there is always a crop factor.
