There is a confusion here between bit depth and bit width, and 
neither has anything to with dynamic range per se. Sensor and capture 
file depth beyond 16 bits is a little pointless at this stage of 
digital photography, while 64 bit data path width is very definitely 
a useful processing parameter. Dynamic range depends largely on the 
(mostly analog) efficiency of the sensor bit buckets, and any 
increase there is hugely beneficial, but that benefit can already be 
seen and exploited in 8 bit jpegs processed on 16bit wide processors.

Since dynamic range, noise floor and low noise - high ISO performance 
are all intimately related, maybe Nikon's new sensor advances will 
also lead to significant benefits in dynamic range, should they make 
that their focus in their hi-res camera.

That could increase dynamic range in
