So the hardware boost for PS4 wasn't very long-lived; 13k for the week ending May 10th according to the front page.
Also, looks like some regular Switch stock finally made it down the pipeline; 3:1 ratio over the Lite.
I think 10 weeks is very long lived. The console has been steady to up YOY since the beginning of March. At its low point the console was -64% Y/Y at the beginning March, now that number is in the ~-30% range.
