This is all hypothetical but interesting idea I had earlier. It may get shot down but it was just a thought.
Nintendo if they wanted to, they don't have to upgrade the switch to make it more powerful. They could actually make docks that have more processing power in it to help power the switch on the TV, then when in handheld mode downgrade the graphics/resolution.
That way you don't have to buy a whole new system, just the dock.
I'm being very vague about this but I think you guys get the gist of it, what do you say SW?
