"The demographic of PS4 and XboxOne is comprised of more mature and hard core gamers."
More mature than what? The demographic is barely different from nintendo's.
I think the games might sell a little more but nintendo would be getting less money per copy because of royalties, would cost more to develop due to multiplatform and they wouldn't be developing on their own hardware.
I guess I could have explained more on that. There's not many M rated games on Wii U or 3DS. PS4 and XBone have those titles. It's very rare for me to see profanity on Nintendo consoles. It was such a huge deal. Even The Angry Video Game Nerd was losing his mind that "Fuck" was in a licensed Nintendo game. Profanity, Sex (cough, Witcher 3), and M Rated games in general are more mature things than a plumber eating shrooms and driving go karts.
I agree that they wouldn't be making as much on their software titles due to developing on non-proprietarty hardware. It would also be hard for them to develop their unique games on a system that they'd have to learn at the same time as everyone else.
