I doubt that a Splatoon port will release on NX. If Nintendo wants to bring Splatoon to NX, they will bring it as a Remaster with new content or they will make Splatoon 2 on NX.

Anyway back to the topic. If they port Splatoon on NX, I can imagine that it will sell 7-9M LTD on both consoles. And if NX is a big success (the success Nintendo wants to achieve with NX) then I could imagine 9-11M LTD.

This game gets far more credit than it deserves. NX will do as badly as WiiU and Splat2oon will do the same, or worse, than the first game.

Better than the obsessive downplaying that it was getting before it was released, or some negative spins after its release!

As for NX do you know what it is? I don't think so, then don't perconceive that it will be a commercial flop...

I don't think so, but 5-6M seems possible.

Yes if NX is successful and especially if it a launch title

I could see that happening, sure. It'll require the NX to be a fair bit more succesful than the Wii U (Maybe a 25 million LTD) but it certainly isn't out of reach.

Eh, it's simply my opinion. I didn't know much about WiiU but I called it to be the flop it's been. Nintendo ruined the brand when Wii became such a success. If the company is ever to see such success again it'll have to make a Wii clone. So much for innovation. 

Im talking  about splatoon 2 not splatoon 1 :p

It's possible, but the NX would need to be far more successful than the WiiU for that to happen.

Japan 1mil with horrible HC user base. If on HH, just imagine :o
