I think Nikon might be shooting itself in the foot.
I would say Nikon has us all on the hook.
I think Pierre hit the nail on the head - people make choices how much to spend on their tools, hobbies and passions. Just because people choose (and it is a choice) not to spend 2, 3, or $6,000 on a camera does not equal a company shooting itself in the foot. Shooting itself in the foot would be choosing to loose money just to hopefully pacify some customers.
How low would it have to be priced? There are people on here screaming about the new 50mm 1.8 being too expensive at $225. When the D400 comes out, I'm willing to bet it will be close to $2000, and I'm sure people will scream about that. Point being, no matter what price Nikon needs to charge, there will be those who want it cheaper so it fits their choice of what they are willing to spend.
$8000 for a carbon-fibre bicycle? That is almost 3x the cost of my first car in the mid 90's.
