Nah, PS4 at the least will be 130 million. It'll be in the 130-150 million range. 

Of course PS4 will sell much more

Switch can sell well. The thing is that this we be Nintendo's only platform for the next six years. Assuming Nintendo does not make any major mistakes the sales curve for the Switch should resemble the NES. For those who do not know the NES started very slow but keep building up until it peaked around 1990 to 1991. In Europe I think it peaked in 1992. Out of all the Nintendo consoles I see the NES being the closest relative. Handheld wise I see the DS as the closest.

So it has a lot of potential. I pegged at around 120 million to 130 million. It is going to a lot closer than what most think.

What makes you think the Switch will peak late?

Why use the misconcept of the DVD?

Was the DVD function that made it sell that much even after X360 released? Was the DVD functionality that made it sell more SW than any other system?

PS2 HW was great for the pricepoint and time of release. It was released for small loss as usual, and GC+XB were only stronger because they launched later and could use more advanced tech.

PS2 had Dreamcast, GC and Xbox to compete against, but even so it didn't even considered them competition when it smoked they out.

If you want to use DVD to justify the sales why not use netflix and BD for PS4?

It is true that Nintendo home consoles usually peak early, but the question is "why".  Why do their home consoles peak early?

The answer is that the release schedule of their games is front loaded.  They release a bunch of games for say, a home console, for a couple of years and then they focus their resources on handheld games to prepare for their next handheld launch.  Back and forth their developers go making home games for 2-3 years, then handheld games for a couple of years.

The Switch is different, because all of their developers are making games for one console.  They will have a steady stream of games for the console's lifetime, so it is not unreasonable to think that the Switch will not be front loaded like Nintendo's other home consoles.  (Of course Nintendo's handheld consoles are never front loaded, because they always have lots of 3rd party games too.  Don't be surprised if the Switch has plenty of 3rd party games.)

Ding Ding! This is the correct answer. I couldn't have said it better myself. We haven't had Nintendo support only one platform since the 80s. The Switch having this advantage is not new. The NES had it as well. 3rd parties came late to the NES too back in the day. I think most of the best 3rd party NES games came in the second half of the systems life. Like 1988 or later. Expect the same to happen to the Switch.

Yea, I agree. I think the Switch is going to end up selling around what the 3DS ends up at, ~75M. It should end up doing well in the US, but not quite matching the PS4, while definitely beating it in Japan. EU and Others is where the PS4 is really going to build its lead over the Switch. I'm guessing the PS4 is going to end up ~125M-145M.

A big reason is I see the Switch peaking sooner than the PS4. Once the Switch hits $199, that will most likely be its peak year. I'm guessing 2019. This will be due to $199 really being the last hurdle when it comes to price. After that, price really doesn't become a problem so future cuts bring only modest bumps, and the rest of the sales must be carried by SW, 1st and 3rd party. Nintendo is going to have the 1st party, but will still be lacking in the 3rd party. That may not be an issue this close to release, but as the years go on it will be a bigger problem when it is getting fewer and fewer of the big releases. I also think Nintendo is going to start to be lacking on the 1st party in the last year or so before the release of the successor to the Switch, which will most likely be out in 2022.

Sony, on the other hand, is looking at a very good 5th year. One that could be its largest. A cut to $199, with possibly a $149-$179 SKU for BF week. The Pro will be cut to $349, most likely with a $299 SKU for BF. They'll have all the big 3rd party releases, with quite a few big 1st party ones, as well. Even if it isn't their largest, it won't be very far from the numbers of this FY.

Well, historically, Nintendo hardware have strong peaks but shorter life span. 

While Sony hardware have a well distributed sales through its life, so, they don't have strong peaks. 

So, I'd bet in ps4 with 6years above 17M( this year at 20), while switch should have only 3 or 4. Most above 20M. 

Lol, it's always hilarious to see people try and use the DVD excuse over and over.  The fact is, as I proved in a thread of mine, the DVD had little to absolutely nothing to do with the success of the PS2.  DVD players were available for much cheaper than the $299 the PS2 launched for in 2000.  If I remember correctly from that thread, you could get one for $99-$149 that year, and the following year you could get one for $49-$69. 

The reality was that the PS2 helped DVD sales, not the other way around.  DVD sales went up AFTER the PS2 launched in pretty much every region.  They weren't doing great and then the PS2 launched and people were like, "Hey, these DVDs are great, let's get a PS2 that can play them and game."  It was gamers buying the PS2 saying, "Hey, the PS2 can also play DVDs, I guess we should pick up a couple to test them out."
