3DS launched 5.5 years ago and was not considered sucessful along with the Wii U and Nintendo still has a 15mil consoles lead this gen over the highly sucessful Sony.

Unless they screw up BIG TIME, the only answer to OP is forever.

nx is a handheld with a tv add on mod. So you can't compare them. But for the sake of the question I say the second the ps4 pro and scropio come out nintendos lead will be gone. lol maybe take 3 months.

Hmmm new account clearly being against Nintendo in a harsh, almost trolling way...if you are legit, welcome!

Anyway can you please post a link that provides us with the proof that the NX is weaker than the X1 that is not rumor or speculation?  From the sounds of it, you clearly have the specs and possibly the console itself.

I will wait...☺

EDIT:  Just noticed he was banned for trolling...guess I better not wait too long!  😅

I think it's still a 8th gen device. Or maybe a 9th gen handheld?

I do apologize for the censorship but the post was just so big and I wanted to highlight the bolded. Regarding the bolded part, my experience is completely different. In 2014 and 2015 there were people talking the possibility of upgrades and how the traditional console generations would lose their meaning. Problem is, these talks, these people who actually had correct vision how the console landscape would change, got ignored. That's it. They got buried six feet under by the masses. It is always like that, I've seen it many times in different topics not just in gaming.

You wrote a fine history lesson for console generations and for that purpose will the term "generation" continue to exist, for history lessons. Look at this thread, look how confusing has it become. It used to be clear cut and easy to understand for everyone, there was no misundertanding, the term served a purpose in all kinds of discussions whether it was casual or hardcore. But now, the term has weakened and it will continue to do so looking at the console market. Look at phones, televisions, computers, these can be divided into generations but yet nobody does it anymore, it's become irrelevant to the discussion and I believe that will happen to console market.

It will keep the lead for zero seconds.

So you're saying its time to hand out the pitchforks and torches and go after Nintendo for screwing with our nice neat generations?  I'm not saying that because I'm overstocked on pitchforks and torches or anything ...

I believe the only way to use the word generations about consoles, is grouping them as a unit.
That means, gens only make sense when you look at the competition as well.

If NX spends most of its life cycle competeing against Xbox One & Playstation 4, that means its NOT a 9th gen system.

So the answear is "no time" , because its a late 8th gen system by nintendo.
Its competeing against PS4 + XB1, and its just very late to the party.

Wii U is like a Gen 7.5 console and NX sounds like a weak Gen 8 console. I'm not sure what it's going to compare against.

I can say that and I did. I didnt mean to be rude about it. Im just asking why its so hard to understand it.
