Design the successor to the 3DS

[Bofferbrauer2]

Still a hybrid, but a different one:

A switch phone with 5-5.5 inch display. To make it thin enough it will loose the ability to read cartridges, so it's going to be digital only, and the Joycons are non-removable and actually part of the case. On the plus side, it adds some productivity apps to Nintendos game library and of course complete phone functionality. And it comes with an audio jack for headsets.

To reduce the power consumption it will come with an evolution of Tegra, but clocked down to match more or less original Switch performance, and clocked down even further outside gaming so it will last for a whole day at least when not gaming all the time.

And I expect it to come out around 2020 at the earliest, after they came with an XL/LL and an upgraded Switch. So basically the Switch Phone would be analogue to a 2DS in the 3DS lineup.
