Is 'people who want a FULLY magnesium body' a unique market?
Perhaps it's just a mistranslation or misinterpretation, but 'only... address a market which would be unique' doesn't seem to be a good way to decide whether or not to sell most of your products.
Is the FA 50/1.4 really 'unique'? Is the 18-55? Is the k-5's battery unique? Pentax sells all those things, so it seems to be at least a little arbitrary to apply the 'address a market which would be unique' standard to a camera, especially when the k-5 and the k-x weren't decidely UNIQUE, and most certainly did not address a unique market, and yet were fantastic hits (and awesome cameras!) that grew the brand.
