My first prediction! I'll probably be extremely wrong lol.
Looking at how high the switch rose on amazon after the restock suggests that demand is still really high, and while it's obviously not representative of nationwide stock levels, I think there will be More of a correlation than others think, as switch production is supposedly increasing around this month (However - few notable releases for switch, and more for PS4). With that in mind:
Switch: 300k
PS4: 295k
XB1: 160k
3ds: 150k
SNES: 310k
