Wasn't expecting it to actually be called "Switch 2", but I'm glad they stuck to a name that makes sense.
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.
"Super Switch" would've been pretty bad-ass.
