“We are making improvements to the fuel-burn performance and the payload/range and, at same time, adding features and functionality to allow the airlines to continue to keep the aircraft fresh in their fleets,” says 777 Chief Project Engineer and Vice President Larry Schneider. The upgrades, many of which will be retrofittable, come as Boeing continues to pursue new sales of the current-generation twin to help maintain the 8.3-per-month production rate until the transition to the 777X at the end of the decade.
Boeing is also reducing the drag of the 777 by making a series of aerodynamic changes to the wing based on design work conducted for the 787 and, perhaps surprisingly, the long-canceled McDonnell Douglas MD-12. The most visible change, which sharp-eyed observers will also be able to spot from below the aircraft, is a 787-inspired inboard flap fairing redesign.

Since the B777 already have a ultra low drag profile it probably will be even harder to slow down on approach.
But in todays aviation fuel economy is everything.
Yeah but they will always have flaps and gear for that. lol
Spoilers will do fine.
Those massive 777 engines will slow it down fast enough
