Since you're decided already to go Yamaha either way - I wouldn't fish around for any more information here but rather go with what the Yamaha dealer represents to you as *fact*

Otherwise it could lead to a conflict of whom to *believe* in the end.

Which isn't a good feeling for starting any deal.

Copngratulations in advance and - good luck!
