So our earlier predictions were not that far off compared to the real numbers.
Only a few major differences.
Jan- Spot on
Feb- ~5k XB1
March- ~10k PS4, ~7k XB1
April- ~7k PS4, ~17k XB1
Also of note, with the new leaked charts and Aquamarine charts we have pretty much exact data for PS4, XB1, Switch. So at least with US and Japan we know everything.
