Maybe in your mind it is, but, more realistically it is about Yamaha's analysis of the market and their decision not to enter a portion of the market that isn't proven to be economically viable.

A wise company does not make anything unless it is shown to be economically viable.

Clearly, you can't (or won't) grasp simple basic marketing.

Spalding, Gary and I have explained it quite well to you, but it seems to be beyond your comprehension...you just seem bent on trying to prove a point that has no basis in reality.

Good luck.
