How could Nintendo implement a Switch Pro?

So a Tegra X1 or X2 in the tablet and an additional Tegra X1 or X2 in the dock?

How would both SoCs sync the data? Over the same USB-C port which already handles the HDMI stream and the network stream?

Would the SoCs sync with Tegra X1 performance even if one of them is a Tegra X2? Or would both run with max performance?

Would the SoC-dock come with its own memory or would it share the tablet memory with the other SoC?

If the SoC dock has its own memory: What happens if you undock the Switch?

Good questions. You clearly thought about this more than I did.

Docking would be the same as now (passthrough) but with an option to restart in high performance mode (ie use the dock's Tegra).

Undocking would stream to the tablet while the game was reloading into portable mode in the background. The game could already be loaded then put into sleep mode on the tablet speeding things up a bit. No-one actually switches mid-game anyway, do they?

Just to be clear, there's no combining of GPU power. The dock wouldn't be supplemental, it would be it's own console. A TX1 dock would be pretty pointless for better graphics without a serious overclock but as a budget/second dedicated home console with a DVD player and some HDD space, $149ish wouldn't be bad especially if you can get $50 back for the current dock.
