With the Sony fiscal numbers, i think the PS4 is pretty much dying faster than we thought, hardware wise. Sony seem pretty subborn on their 9 million and won't ship more. If they didn't lower the price and aren't shipping more, maybe it's cause the PS5 price will be pretty expensive. So i think the PS4 is destined to die around 125 more or less, and i don't see it reaching 130 millions unless they make a move out of nowhere.
Let's wait for Q1 numbers from Nintendo, but i think they will indicate pretty big stuff. I do think the Switch could end up in that 120-125 million range.
