Last quarter Switch sold 2.46M units compared to 2.6M for the PS4, PS4 also outsold if for the entire last fiscal year. I think it's rather impressive that +5 years after launch, 2 years after Switch it is still on top, with the price still officially being at $300. Sony has stopped relying on price cuts to keep momentum and shifted system selling incentives to big fancy games, plus a mid gen upgrade. And while Sony is forecasting 16M units this year vs Nintendo's 18M, even if Sony has a history of underestimating their numbers and Nintendo overestimating, I think Switch will probably finally overtake it this year. Sony is expecting PS4 to be at +110M units this time next year, half a year before the PS5 is expected to launch. I think PS5 is gonna continue where the PS4 left off but I doubt it's gonna be as successful, Sony don't have some of the A team execs they started this gen with anymore.
