Its just the marketing game.
The truth is DR is very misunderstood and there is no standard for testing it .. so a manufacturer can claim anything they want.
The camera manufactures don't even state a given lens or light/weather condition.
Some photographers claim they get 6 - 8 stops DR in the field and I think that might be about right.
The problem lies in the usability of this dynamic range; if too few bits are spread over too great of a tonal range, then this can lead to image posterization. On the other hand, displayable dynamic range depends on the gamma correction or tonal curve implied by the image file, or used by the video card and display device ..
