How should the ps4 pro be selling 

I don't know 🤔

PS4 at 60 million.

Wii at 100 million. You predict Ps4 will sell 20 million less. By your prediction Sony needs to sell less than approximately 20 million units end of life for it to be correct. It will do 80% of that 20 million (16 million) within a year from now. That leaves 4 million units to sell between June 2018 to whenever production of Ps4 ends. So I think you're going to be wrong d:

I guess @ the OP: Sometime end of 2019/early 2020. PS5 comes out holiday 19', we will have sub $200 PS4 prices. Maybe hitting something like $125-$150 for Black Friday of 19'.

my question is, how can people who have had an account on a sales website know so little about sales? boggles the mind, also with idiotic diatribe like "scorpio and da switch gonna scare sony into releasing PS5 early" or other irrelevant and made up crap thats spewed here the discussion gets ruined fast

That "at least 20M less than wii" prediction made me cringe

Why should PS4 sell 10 million in 2020, with PS5 on market going for its second year of life? makes no sense.

Because you are wrong in your ps5 launch date 

No way, Holiday 2019 for sure. 3 years between 4 and Pro, 3 years between Pro and 5. PS4 will still have relevance on a mass market friendly price and compatibility with newer games a la toned down settings. They're based on a x86 PC architecture, scalability should be easy. 

You think PS4 will stop around 80m something?

You do realise they plan on shipping 18m this year? so march 2018, they will be over 78m!

Right? next year march it will be at 78m.

By the holidays in 2018, you will be proved wrong.

I'm pretty sure the fact that they no responding means they it will and just trolling because they salty

Not going to happen, sorry.
