The Xbox One S was just an interim upgrade for the Xbox with the main upgrade always going to be Project Scorpio.

We now have the specifications of this new console and it is looking like a beast (still not as good as a PC though)

Inside each system will be a CPU featuring eight custom x86 cores, clocked at 2.3 GHz, a custom GPU with 40 customised compute units clocked at 1172MHz and 12GB of GDDR5 RAM. Players will also have 1TB, 2.5-inch hard drive to play around with, and a 4K UHD Blu-ray drive.

The 12GB of memory is shared across the system but the Scorpio now has 8GB to use for gaming which the One and One S only had 5GB. Combined with the memory bandwidth upgrade this should allow the system to handle true 4K gaming. This was the case for two outlets, who saw Forza Motorsport demo running at native 4K and 60 frames per second.

The new Xbox will have an internal power supply, for instance, like the Xbox One S. It will also support Dolby Atmos and a proprietary format called HRTF, developed by the Microsoft Hololens team.
