Playstation PlayStation 5 and Project Scarlett: Real threats to the Switch?

At this time next year, we will likely be just weeks away from the launch of the next-gen systems, the PlayStation 5 and Xbox One successor Project Scarlett. Neither console has been fully unveiled as of this moment, but that will no doubt change in the coming months. Sony and Microsoft have at least both provided a release window (holidays 2020) along with an overview of the specs of each of the new machines. All in all, they appear to be very powerful. Regardless, just the fact that theyre the all-new systems on the market will be enough to generate a huge wave of interest from consumers. That leaves the question: How worried should Nintendo be for the Switch?
