Well, one of the new rumors going around is that Nintendo is planning to update the dock, rather than the Switch itself. So, the dock would upscale the games without a new model of Switch needing to be released. In that case, I think original Switch owners wouldn't have to worry about being barred from buying certain Switch games in the future. The OG models just wouldn't benefit from the upscaling that the new Docks would be capable of. If the rumor is true, and if I'm understanding what it implies that is.
dock upgrade is a wrong move.
Switch power is a dynamic style of play. You choose when and how you play your games. A powerful dock is a wrong move.
