Yup you are crazy :)
Seriously though, if by the fall of 2016 sony can get the PS4 down in price to $199, and this gen ends in 2020, then it stands a very very very good chance of having sold around 130M in 2020.
Personally, if I were sony, I would drop the price to $200 today and bite a $160 loss on every PS4 sold. I'd probably go bankrupt too.
