Will the Nintendo Switch overtake the PS4 in terms of sales worldwide?

Let's say PS4 will end up at 125-130 millions
The Switch should be at around 77 millions after 4 years.

I think after this year doing 23-25 millions without a price cut and maybe a new model, I dont see it free falling in the coming years since this situation is completely different from the Wii (Arrival of HD TV in the mainstream market, people actually not really liking the system while the switch is beloved.)

So let's say it can pull off a 19 millions next year and a 16 millions after that which is probably a rough case scenario.. then it ends up at 112 millions after 6 years. Nintendo speaks of making it longer than usual, and I believe them since they now have only 1 system so they will make it work while they have a successful one, it could have another 11 and 6 million years putting it around the same range as the PS4.

So it might seem far but it is really possible. It will probably be a tight, last minute victory
