PS4 will beat Switch + 3DS probably every single year, 3DS sales will enter the nose dive point after this holidays so this is actually the only year there is a chance for both combined beat the PS4, after that it'll be basically PS4 vs Switch and PS4 will keep beating it until the PS5 comes.

Pretty bold statement, especially because at end of life of console and before new console arrives, console have huge drop is sales.
