Let's forget about Nikon for a second.
Just consider that at a time when the 5DIII is #14 on Amazon, the 6D is #29.

As an 18-year marketing veteran, you surely understand price elasticity of demand.
So, when a $3K product is #14 on a best sellers' list and a $2K product is #29, what does this tell you about the $2K product.

In layman's terms, I'd describe the $2K product in question as ... a dud.
How would you describe it, Mr. Marketing Veteran ;).
