How many SZ members want a 76 note Yamaha, (The Vocal Minority) and how many millions of sales have been made with 61 notes (The Silent Majority) and you can see that the arguments for 76 notes are nonsensical in sales terms.
As to the cost of a 76, do a search in previous posts, and you will find that contrary to what the layman thinks, it would NOT be cheap to produce.
