The speed of the SSD in the new MacBook Pro is from more than just NVMe support. Apple's 338S00199 SSD controller is the key to the operation, allowing for throughput on a portable SSD never before seen.
The next generation of flash media storage, called 3D XPoint, and branded as Optane by Intel, is compatible with the NVMe storage protocol that Apple already uses in some of its MacBooks, including the MacBook Pro. The new technology could be used in a new MacBook Pro in 2017, controlled by either the current Apple SSD custom controller, or a future version of same as the underlying technologies are compatible now.
