Couple of ducks have to be in a row before I would buy a second console.
1. The console I currently have has no games on it that I want to play. Since I have a PS4, this is not going to happen.
2. The console under consideration has at least 3 exclusive games that I am interested in.
So, the only console in the running would be something from Nintendo, the Switch or a 3DS. But there is no single game that would cause me to purchase a console. The exception might be a launch console, but in the past I have always waited until a launch console had a couple of games or more I really wanted to play.
