I mean, VGC has constantly adjusted their USA figures to be more in line with NPD whenever it was needed and the information existed. VGC has the PS4 at ~35m and that shouldn't be far off from official NPD figures (that nobody here has access to). So Switch has passed the 35m mark in the USA.
I think in the thread about the gap charts, VGC had Switch passing the PS4 in the USA in March, so one month earlier. This means the LTD figures for the PS4 and Switch are slightly off on VGC, but it's not a dramatic difference.
I ended up adjusting our US estimates for 2022 and we now have Switch topping the PS4 in early April instead of March to match what NPD has stated.
