So other than one manufacturer saying that the market wants 61 keys more than 76 keys, there is no “official” or “real” or “actual” proof or evidence to validate that claim.

What can be more "official" than the information provided by music dealers and customer surveys?

Do you think these big companies need to prove anything to you?
