Is Sony responsible for the PS4's great sales, or are Nintendo/Microsoft?

Why would Nintendo's failures have anything to do with PS4's success?

If we're playing tennis, it's pretty freaking easy for me to win if you keep serving the ball out of bounds or into the net. 

Nintendo repeatedly shoots themselves in the foot, competing against them in the console space is easy. 

They have completely different audiences. It's like they're playing on different courts.

Nintendo doesn't have an audience this generation other than "Nintendo lifers", which is a small demographic overall. The kids and especially the casual markets have both ditched them. 

Nintendo's kind of cornered themselves into being irrelevant in the console space ... which I'm sure suits Sony just fine aside from their concern that a weakened Nintendo doesn't bring in as many kids nowadays (future Sony customers) because they're going crazy over tablets/phone games.
