Well, if the PS4 is only supposed to drop by 2M in this FY, then Sony has to do something to slow it down, and slow it down a lot I think. Because at the current rate, 14M would be a much more realistic target.
My thoughts as well, something needs to happen as it seems both USA and Japan are dropping quite a bit.
Something has to be up their sleeves for 2019. TloU2 might be the game, and a super slim might be the system that makes them reach their goal.
