Its important to note that patent designs rarely have the final design in them. Most of the time they draw only a very generic, very basic design with the proper technical features. It may look like this and have Switch BC, but it might be completely different.
Also, as I have been saying all along, Nintendo definitely delayed Metroid Prime 4 (a game announced extremely early into the Switch’s lifecycle) to be a Switch successor launch title.
I can only hope their new console gets an emulator relatively quickly, because Nintendo keeps making hardware that is severely outdated and underpowered before it even comes out.
