As said it’s useless and inaccurate information, but just as a fun exercise😎……..
When I think of the size of the resource to design, market etc a Tyros, it’s hard to imagine a corporation the size of Yamaha would bother unless total sales for each TOTL model were in several millions of dollars. So if we say $5m net total revenue per model, and there were five models, that is $25m in Tyros sales. At today’s value after dealer mark up shipping and other costs, Yamaha maybe nets about $3000 revenue per unit at today’s value. So that $25m would be over 8000 units.
Probably total rubbish, but maybe as good a guess as anyone 🥸🥸🥸
