Vgchartz are just made up numbers
Yes, made up numbers which are less then what the PS4 has actually sold.
How this thread turned into a ps4 vs switch argument is beyond me.
Predictions (Made July 2019)
LTD: PS4 - 130m, Switch - 110m, XBO - 52m 2019 : PS4 - 15m, Switch - 18.8m, XBO - 4.8m 2020: Switch - 22m (Peak Year)
Switch lite really screwed up my Switch prediction this year! Looks like it's going to be about 19.5m-20m for the Switch in 2019, 14.3m for PS4.
