Kind of interesting how the improved Switch (staggered thru Aug) & Lite (Sept 20) both released in a 2 month window of each other just like PS4 Slim (Sept 15) & Pro (Nov 10) did back in 2016.
Did the improved Switch improve sales? I didn't think so looking at the numbers. They didn't even market it. I bet there are many more people that knew about the Wii U over the better battery Switch, and that is saying something. The PS4 pro, everyone and the mothers knew about. So those aren't really fairly comparable.
