Personally I doubt it. I expect it to get the Mario Kart/Smash treatment with just one per console

The thing is though that Splatoon 2 seems more like Splatoon 1.5 in a lot of ways. Just a lot of tweaks and polishing to the original game, not a lot of big changes, since I'm sure they wanted to get a Splatoon game out on Switch asap. So I wouldn't be surprised to see Splatoon 3 in a couple years that is more of the true evolution of the franchise. 

I'd say they wanted it out asap to avoid any hole in the lineup for this year to avoid the infamous Wii U droughts on the Switch. Splatoon 2 was easy because not too much had to be changed on a technical standpoint from the original game, being able to retain most assets, just maybe polishing them up a bit. Otherwise there wouldn't have been any big game release between Arms and Fire Emblem Warriors/Pokkén tournament late september (don't think they knew a release date yet for Mario & rabbits at that point), so a very dry summer for the Switch.

Splatoon 3 will come, but I doubt it will come this decade

Right, it was an easy game for them to do and served the purposes of filling in gaps and getting one of Nintendo's biggest successess this decade onto a platform which will quickly have a bigger install base than Wii U ever did. Which is my point that it doesn't seem like the true sequel in a lot of ways, and they may very well have Splatoon 3 out by 2020, which would definitely still be in the Switch's lifecycle. 

I think Splatoon 2 has more than enough, though, to be deemed a true sequel. Salmon Run, Legend Mode, new weapons, new stages, new merch, and a continuing story from the first game. Of course add on LAN options, improved online and local multiplayer options, can make it more of an enhanced update sequel, but nevertheless, it's still a true sequel in its own right. It's not necessarily from Smash 64 to Melee, but I'd argue it's not just a simple update since you couldn't do some of these options on Wii U due to utilizing the game pad, which sorta limited local multiplayer among other things and the recent direct, and even the previous ones, showed there are new gameplay options to make the game a sequel and not just an enhanced port like Mario Kart 8 Deluxe.

Its pulling some insane numbers in COMG right now...... For now I say around 2.5mil - 3mil LT. If the Monster Hunter, Pokemon and Animal Crossing fans gets the Switch and are also interested in this......... then OH BOY!

The Switch would need to sell well over 20 million lifetime in Japan like the 3DS which I see very achievable since it will be the only dedicated gaming handheld on the market there in the next year or so, but even then 5 million is outselling the best 3DS game in Japan Animal Crossing New Leaf which sold 4.5 million going by VGChartz numbers, so... right now as bold as I can go is it selling over 3 million in Japan but who knows, anything can happen.

Did you know Splatoon is the best selling home console game between ps4/xbone and wiiu in Japan? Did you know Splatoon sold 1.5 million units on a 3.3 million userbase (Japan)? Do you believe splatoon 2 won't sell more on switch than it did on wiiu? 

That being said, dragon Quest 7 warriors is the most sold dragon Quest game on 3ds with 1.3 million units...the first splatoon already beat it. 

Monster Hunter 4 sold 3.4 million units. I don't think splatoon 2 will surpass it but I think it can definitely get close. I think you underestimate how big splatoon is over there. 

Except massive attach rates are sort of common on underperforming consoles.*  Actually, I just made that up, now I'll have to go check... :)  But seriously, Super Mario Galaxy didn't magically sell 25 million just because it was on a much better-selling console than Super Mario 64.

I think 5 million in Japan alone is way out there, but I do hope for Splatoon 2 to have a much better showing worldwide thanks to Switch's improved sales.  I'm thinking more like 10 million, though.

*Hmm, checked a few series like Mario, Halo, GTA and it's kind of inconclusive.  If we want to take a pretty optimistic Mario Kart type scenario for Splatoon, then 3.5-4 million might actually be feasible for Japan, that would be nice to see.  I'd be shocked to see >4 million.

It's time, guys. Splatoon 2 already sold over 2 million in Japan.

yeah, maybe 2 million in 6 months. There was no way for selling 5 million in such a short time...

Well man, it's over 2 million already, and it sold over 100k last week, so unless his legs crash super hard, well, 3 million is pretty crazy, let alone 2.5 million.

By the way, Animal Crossing has sold over 5 million including digital. And Splatoon is way head of him...

Was this comment about Splatoon 1, i hope? Because then this looks spot on...

Eh, i doubt this is either bold or crazy at this point.

3 million now is impossible. Anything under 4 million is.

Indeed. :D

Well, now we know Splatoon 2 will easy surpass Monster Hunter 4.

Mike321 said: I think that's impossible even for such a surprise hit like splatoon but hey you never know

Still impossible?

Best comment of the thread.

yeah. In 6 months. Now, let's see how numbers are in 5 years.

less than 500k to go for that "possible" 2.5 million mark.

"Wishful thinking" like the first game selling 1.75 million, i guess.

Still expect that?

Well, now we know for sure it won't sell under 4 million.

Well, now we know it will surely get close at the very least. About your 2.4-3.2 million prediction... uh...

Well, 2 million are already a thing, with this trend, 3 million will probabily happen for the first half of 2018.

I think the IP is already grow, way too much actually. :p

Yeah, 2 million sold in 6 months was very possible, as 5 million worldwide. Now, let's see how much it sell in the nexts years!
