PS4 wins.

Too early to talk about switch, but i think it will not reach the 100 mark.

I'd reserve judgment on this until we see how Labo does, and what they have for E3.

Launch aligned? Switch. PS4 is a big success, but it will take almost 6 years for it to cross the mark. I think Switch can do it in less than 5, so I’ll go with it.

Thread title should be updated. It sounds like it’s asking which one will reach the milestone first.

"Certainly will be the PS4" meanwhile the only numbers we have from the switch, it is beating the PS4 launch aligned.

People are always underestimating Switch, which is why it's funny to take bets and deliver the crow later.

In my opinion, Switch as a fair shot at making it to 100 million faster. It's doing amazing in every territory, has huge system sellers for all audience coming and stuff like Labo. It also needs to be launched in some markets. If it can do 15 millions first year and over 20 million in the second one (if Nintendo's predictions are doable), then i don't think it will take long to reach 100 millions once Nintendo starts getting aggressive with the price/bundle/deals. 

Switch might not make it. I expect 3 or 4 big years and then for sales to slow.

Actually it will probably ship something around 17m on its first full year (which ends at the beginning of March). By the end of this year's first quarter (March), it should be near 18m. The 20m figure is their expectations for the next FY which is from April 2018 to March 2019. What I mean is... it will be at least around 38m by the end of its second year. That's quite impressive if you ask me. xD

Excellent, thanks.

PS4 and it won't even be close, switch won't do 100 million.

As a Sony Pony, I'd like to make a comment in Switch's favor (or really, an anecdote).

So as an example subject, I'm going to use my nephews. They're 8 and 9, and are huge gamers thanks in part to their uncle having all the coolest shit and wanting them to have it as well. This past Christmas, they each got a Switch. Why? Because regardless of what Nintendo fans and Nintendo themselves say, this console is going to sell like it was a handheld. That means one for each, so that way they can make full use of the platform without fighting over it. I would imagine many households have and will emulate the same thing, where those same households would likely only have one PS4 or Xbox. In fact, that's the case at my nephew's home: One PS4, and two Switches.

So Switch has a distinct advantage over the PS4, and assuming it can maintain steam and not fall victim to the Nintendo condition of not keeping up with 3rd Parties I think it has a solid chance at beating PS4 in aligned launch sales to that 100m mark.
