Here is the week 31 update in terms of the two big consoles in Japan's path to be able to reach the commonly stated (in these sales threads) estimates for 2018 sales (2 mil for PS4, 4 mil for Switch) .
| TWS | GD | YTD | AWN (Change) | |
| PS4 | 19,002 | -23,532 | 1,083,249 | 43,654 (+1120) |
| Switch | 50,799 | -66,758 | 1,464,530 | 120,736 (+3008) |
TWS - This week's sales
GD - Goal differential, the difference between the average week needed from last week compared to this week's sales
YTD - Units sold in 2018 so far including this week's sales
AWN - Average weekly sales needed to reach the estimate for the console.
Slight bump for both systems. PS4 needs to average ~45k over the remaining 20 weeks to hit its goal and Switch needs to average ~120k to hit its goal. Obon should take effect in Weeks 32 and 33, so looking forward to see how that changes things.
