Nikon should be hell bent on satisfying their customers rather than chasing profits.
I think they need to focus on both

and upon those occasions where focussing on one of them also caters to the other, everybody is most pleased. But they are not always the same, and focussing on the business side is as important as focussing on the 'customer wish' side, and sometimes it is even more important to keep a company alive. And I guess we all want a company who makes great cameras such as Nikon to survive.
I think the success of the D800 shows that Nikon's deciders made the right decision, and Nikons developers and engineers did a great job. The success of the D800 speaks for itself, so I'm sorry for all those who wish it would have been a different camera, but apparently Nikon found a lot of people who like the D800, so all we can say is they did a good job. They didn't make
everybody happy, but they found a lot of customers, sold their D800 very well, so the D800 is a job well done, a success story for the company Nikon.
So if Nikon people really monitor this thread - I'd like to tell them: job well done for me! Maybe you need to create another camera for decigallen and others who wanted a successor to the D700, but for me, the D800 (and the D600 minus the sensor dirt issue which is not being dealt with appropriately) is a great camera. I bought it despite the 36mp rather than because of them, but once I had it, I deeply appreciated the good work that has been done on designing and making this camera, in all its aspects.
Surely the reason why a D4 costs more is because it costs more to make and develop. ie. the profit margin shouldn't be dissimilar to that of the d800.
I think in most areas, the profit margins of top end models are usually higher - you don't only pay for the hard- and software, you also pay for having the best of the best, the reputation, the prestige. For that reason, I'd never buy a top model. With cameras like the D4, of course, they have features the pros really need, and there is no option other than buying those top models. So maybe the pricing schemes are different with cameras than what I think, but I doubt it.
