This is all insane...

If Yamaha ARE marketing to the 'home' user, why is keyboard size of any matter whatsoever? They don't move it around much and generally go for 88 keys if they DON'T buy an arranger.

If they are selling to pros, well, PLENTY of them want a 76.

Just who in heck IS Yamaha's 'target customer'? Someone who gigs multiple times a day, and needs a small, lightweight arranger to toss in the back of their minicar? I would be prepared to say that is Yamaha's SMALLEST group, there!

This stinks FAR more of internal division politics - "OK, DGX line gets more keys, PSR line gets better voices" rather than any serious attempt to actually give the customers what they want...
