The Switch is a hugely popular console, and we're likely getting a 4K version at some point. But, what about the future of Nintendo in general, will Nintendo ever make a traditional console again? Or will it forever be a console/handheld hybrid?
They wanted to merge their markets of handheld and console which is why the Switch was introduced. I can't see them going away from this. They basically have the market for this. Though the Steam Deck might actually be a competing handheld. We will have to wait and see!
