I recall reading a roadmap for camera sensors, this might be folklore it was a long time ago, the takeaway was that they had the technology for the 100mp sensor and the roadmap showed how they would maximise profit using a 20 year curve working up to the release of the final sensor, by which time a new method would meet that curve to continue their dominance, if I had AGI, I would let it out in very small drips.
Just because we have the ability to move individual atoms around, doesnt mean its affordable to do so. It probably would have been pretty expensive (and low yield, and cumbersom, and error prone) to make a 100mp camera in 2004.
Fair, it may well have been a roadmap based on some kind of theoretical limit on the technology, also, I am fairly old, so 10mp was probably more likely!
