And this is coming from someone who owns a Wii U and 3ds, I just don't know anybody (including me) that isn't that psyched for the Switch.
I know people are going to say "Well I am" and yes I'm sure plenty of people online are hyped for it, but nobody in my town even really knows what a Switch is and those that do don't care for it.
Oh? So everyone you know is psyched? :P
It's not gonna be what people here hope it to become, but I think 25mln is a safe minimal number it will sell.
