Casio sold plenty of CZ-1's, VZ-1's and even a few FZ-1's too, all the while suffering from that same assumed inferiority complex. Even back then, keyboard players didn't CARE whether it had Casio on the front panel. Why would they care any more now?
The Privia has already demonstrated that Casio don't need to rebrand themselves to get respect and sales from the pro players' market. They are one of the hottest, most popular stage pianos (hardly a Casio strong point from years past) out at the moment. I am just unsure WHY, if Casio can get respect in one area of the keyboard market, they can't in the arranger market (or any other they choose to go in)..? All it takes is one killer product.
I don't honestly think this IS opinion... Privia has shown it to be a fact. Without Privia's success, I might be more inclined to think you right, but you are arguing a point that there is direct contrary evidence.
Let's face it. 'What have you done for me lately' is the tune of the industry

Roland USED to be the top dog. TONS of cachet for the name, the logo. But does it get much respect around here?

Not much that I've noticed...

I may have to cover up THAT logo before I cover up a Casio one, these days

If I cared, that is...
