A Nintendo Switch Mini or Nintendo Switch Pocket handheld console could be in the pipeline according to a popular X-based leaker. It seems the source has dug up numerous patents that point to a miniature Switch, although patents often lead to nothing more than the public description of an idea. However, this hasn’t stopped the leaker predicting a price and release date for a Switch Mini.
Yes, that’s the thing.
The 3DS and before had a smaller screens, but games were designed for that screen size.
The Switch is basically to play games designed to run on a TV so there is a limit how small you can go before it becomes hard to play.
