Okay so we wont use weekly.

You said PS4 will be outsold 100% to 300%.

PS4 selling 20 million in a year as the base. You're saying switch will sell 40 to 80 million a year. 

1) He was talking about weekly. Not yearly sales, indeed he said "even if Switch outsell PS4 by 10% every weeks"

2) So you think that for the next 3 years PS4 will sell 20 million and will not slow down even with PS5 release? Seem legit.
