Or maybe the dev kits have an actively cooled X1 for a reason - emulate the extra GPU by overclocking the unit. Devs wouldn't need to worry about the dock, the bus type and anything similar. That's the hardware layer, as long as Nintendo guarantees that performance will be similar, they couldn't care less.
The existing dev kits probably based on the Jetson TX1 board that is actively cooled, which could be replaced with the Pascal equivalent down the road. The Pascal version may or may not need active cooling depending on how well 16nm FinFet translates with the new Tegra. At low wattages I very much doubt it. If it's anything like the Desktop Variants we could be talking decent clock bumps and efficiency increases over Maxwell. The previous 20nm Maxwell Tegra was not Finfet, and it was well known Nvidia was unhappy with how it performed. It had almost no leakage or power consumption improvement over 28nm and had yield problems on top of all of that.
Dynamic clocks and resolutions for video cards and games aren't a new thing either, so seeing a boost in performance and resolution while docked isn't a terribly far fetched idea. I think the odds of the dock providing anything more than connectivity and power are slim to none. Adding USB ports, HDMI and Ethernet would be ideal, but I'm not counting on that last one.
