I thought this was the case back around 2004 or so?
Yeah, I think they only just created the record category or whatever for it. But this has been the case for quite some time.
PS1+PS2 = 260m
NES+SNES+N64+GC = 166m
NES+SNES+N64+GC+Wii = 268m
LTD: PS4 - 125m, Switch - 110m, XBO - 51m
2020: PS4 - 9m, Switch - 22.5m, XBO - 2.5m, PS5 - 4.5m, XBX - 2.8m
