I have always thought that my Sea Dweller 2000 was big and heavy. In comparison, the Deep Sea is HUGE. I became use to the weight after wearing it but I still consider my SD to be a big and heavy watch. In terms of actual diving, I can't see the new Deep Sea watch ever being needed in pressures of that rating. The world record saturation dive is 2,300 some odd feet making the 12,800 depth rating on the Deep Sea overkill.

Quote from a website I found: "The various classes of divers have already reached their physical and physiological safe diving limits. For the recreational diver on air, that limit is 130 feet. For the helmet air supplied commercial diver, it is probably 200 feet. For the mixed gas helmet diver, it is probably 300 feet with a bell-bounce diver going to 600 feet for short durations. For the mixed gas saturation diver, perhaps 2,000 feet. I suspect this should be the limit of pressure to which a human should be subjected. Beyond those lies potential pressure and possibly pressure related tissue volume problems."

Here is from Wiki: The diving depth record for off shore diving was achieved in 1988 by a team of professional divers of the Comex S.A. industrial deep-sea diving company performing pipe line connection exercises at a depth of 534 meters (1752 ft) of sea water (MSW) in the Mediterranean Sea during a record scientific dive.
In 1992 Comex diver Theo Mavrostomos achieved a record of 701 MSW (2300 ft) in an on shore hyperbaric chamber. He took 43 days to complete the scientific record dive, where a hydrogen-helium-oxygen gas mixture was used as breathing gas

I just don't see what Rolex is trying to do with these watches. When the SD 2000 was released, it was NEEDED. The new Deep Sea has no practical use, unless it was produced to greatly reduce the failure rates at pressure by designing a watch to withstand far greater pressures that will ever be used. Thats the ONLY thing I can come up with. I wonder how history will view the Deep Sea. A cherry or lemon, who knows?
