PS4 is always strong no matter what happens.
Switch hardware is disappointing but software is a beast.
? PS4 sales are not strong and its getting outsold 3.5 to 1 by Nintendo Switch. I would say globally PS4 has good numbers, but not in Japan where Switch will surpass its lifetime sales by next year. But this isn't because PS4 is a poor product it has to do with Japanese gamers mainly going towards mobile and portable gaming. PS4 is still doing tremendous in Europe and USA especially considering it is near the end of its life cycle.
