Here is the week 17 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 - 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.
Finally the PS4 shortages are done with. Golden Week also looks to be strong for PS4 so it's making up for all those earlier miserable weeks it seems. Switch rose a little bit and will likely get a big boost for Golden Week as well.
