According to the product specialist

Pros
Great shifting performance, high shift speed and smooth shifting while out of the saddle.
Semi-wireless: there is still a cable connection between the battery, front and rear derailleur. Easier mounting and little chance of cable breakage.
You can bleed the brakes without unscrewing the caliper from the frame. Very handy!
With Di2 electronic shifting, you must adjust the derailleurs once and they will adjust themselves automatically in the future.
10% more space between the pistons, reducing the risk of rotor rubbing.
Best shifting action and best braking performance.
Doseable and very powerful braking.
Improved ergonomics for a pleasant sitting position.
Improved ergonomics for better reach in different hand positions.
Reach adjust is possible.
Electronic disc brake shifter combination for extremely fast, precise shifting and braking.
Improved ergonomics extensively tested by riders on professional cycling teams.
Servowave makes it possible to take braking power and brake metering to an even higher level.
More space in the brake callipers so that the brake discs are less likely to rub off.
Uses the same technology as the Ultegra and Dura-Ace shifters.
Battery life: 3.5 to 4 years.
The brake lever is adjustable in reach.
Cons
80 grams heavier compared to the Dura Ace R9270 disc brake set.

No shift buttons/controls on top of the shifter.
