Yes that's right. Those were the good ole days. I wonder what was complained about then? And complaining is good, make your voice heard - I only prefer some objectivity and logic in the complaints, even for emotional ones. But it was pretty simple for a camera manufacturer back then, just (very gradually, from what I have historically seen) improve your bodies and add newer better lenses. That's how they made money.
It's not how it works today. That is part of the reason why companies like Bronica, Contax, etc, are no longer are around.
If a MF company can't make the money off the back end, it is a very different and difficult equation today.
I also find it interesting to see how slow the pace of development was for cameras back then. That wasn't a bad thing I suppose, fewer upgrade temptations...
