Fact: NO ONE wakes up and thinks "I gotta buy me some iteration today."
Iteration, evolution and low-risk change are means. They are not ends.
I would argue, but would not presume to state as fact, that the large majority of Japanese actually prefer iteration over radical innovation, almost all of the time.
Please point out why you felt I claimed an opinion as a fact, perhaps I could improve my communication with your help.
My work experience tells me that companies commonly put off major updates because of retraining costs and scheduling.
