I think that either of these would sell very well. I think they could manage it too.
I don't think they should flood the market with a bunch of different configurations but I think they should offer one of the two I posted and the current default configuration.
With the savings of removing items from the package, as well as the size savings they would have when shipping these around the world. The box could be smaller and they could fit more in a shipment.
Lol, the dock is essentially a pass-through, and the Joy-Con holder that comes with the console contains no electronics but completes a normal controller. Both are pretty much necessary. So you're talking about a price cut with minimal savings on items that don't cost much to make, and may be very negligible to ship in a slightly larger box.
Removing neither of those low-cost items gets to the price that you want. We're not talking about items that are expensive to produce.
