The prospect of a new revision is an intriguing one; that would certainly be one way to boost sales without taking a price cut.
Problem is, they already have a premium model in the OLED and a cheap mode in the Lite, so what would a new model even look like? I'm of the opinion that a screen-less "Switch home" will never happen, as I feel like they would have done so long ago if they were going to. Maybe a Switch Lite with an OLED screen?
