Just checked on it.
The strongest first 5 months of a year were to DS in 2007 which did 9.125M with may included.
The Switch with the 3rd week of may is at 8.7M for this year, so it have to make a bit over 400K the last week to beat the DS numbers in 2007.. and probably won't.
However it is still very impressive, it beats every other console on every other year.
P.S. Just to report a bug.. the hardware by date chart doesn't show all of the numbers when you put the cursor over the lines .. it shows only some of the console numbers..
I am well aware of the issue with the Hardware by Date graph. It is a height thing, which is why it is only showing 4 consoles instead of 5 or more. I've let TalonMan know about the issue. Hopefully it will get fixed soon. But he is super busy on creating a new front page for us.
