Nintendo tried to bolster there numbers using this tactic by putting vast amounts of water in all there games hoping it'd cause thousands of returns. Unfortunately nobody bought them in the first place to return them.
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.
