It's possibly the most normal successor name they've ever chosen. I like it. I'm picturing someone suggesting "Switch U" and getting thrown out the window like in that meme comic, even though he's often used as the voice of reason...
I still like Famicom > Super Famicom as the best successor name, but having to go back that far to find some competition for naming probably says something.
With the habit they've developed of releasing upgraded versions inside a generation, especially already having Switch OLED, I think Super Switch would be too ambiguous.
