It's pretty unrealistic to expect PS4 having PS2 sales numbers (or even to be above 120 millions units sold),

120m doesnt seem that unrealistic to me.

March 2018 it should be ~78m sold through (I expect them to beat their forecast).

and Imagine thats another year around 18m? Suddenly your not that far from the 100m mark.
