Thinking about it, if they were to start selling dockless Switch systems around the same price as a traditional handheld, then eventually bundle them with AC, Pokemon etc.; they would then have a full-fledged option for the more dedicated handheld audience, removing the barrier of the high entry price point.
They would then be selling both the console/hyrbid version, and a dedicated handheld version, but with the benefit of a shared and stacked library of games. It would almost seem logical that they could sell at twice the rate of a normal system.
A very ambitious target nonetheless, and I'd still have my doubts like most.
