Here is why:
1. Even with exclusives such as Mario Kart 8 and Super smash Bros it will just barely overtake the amount of consoles sold in 2013.
2. The only upcoming main exclusives are Star Fox U and Zelda U. Star Fox U while a fan favourite doesn't sell that many units and therefore won't sell consoles and finally Zelda U is already getting mixed reactions from fans and the Cartoon styled Zelda's don't sell as well usually.
I am sorry, but this is how good it gets.
