It's been hinted and rumored, but not confirmed. I'm just assuming since Nintendo themselves said that a new team is working on the game and Kensuke Tanabe will be the producer.

I'd never agree to a pact like that, thats silly to me. Buy something based off if you want to or not

Ok, I’m sorry, but I have to say something: I find all the Switch port begging for this title and bitterness over this game’s performance is really petty and pathetic.
We got a full blown, 2D Metroid remake (for $40 instead of $60) on a platform that was still performing well and that most, if not all Nintendo fans have. In addition, the game was announced alongside Metroid Prime 4 for the Switch. Most importanlty, the game itself turned out to be great. I bought it, played it, and enjoyed it very much and am looking forward to Prime 4.

So,
+ It was a great game.
+ It’s something fans wanted.
+ It showed that Nintendo is still supporting the series.

It literally had everything a Metroid fan could have possibly wanted at that time following 7 years of nothing in between besides Federation Force. And yet some fans didn’t buy it because:
- It’s on the 3DS... A respectfully solid system with a good install base and a great library of games that is still selling well for a system that is currently in its 8th year and its successor has already been out for a year and a half.
- Because you wanted a Metroid game on the Switch.... When you already know that you’re going to get a (bigger, greater, far more ambitious) Metroid game

I’m sorry, but you guys get no sympathy from me this time. If some of you are still not going to buy a genuine, 2D Metroid game after all that, then I’m beginning to think that maybe Nintendo is not the problem.

Metroid has always been given more importance on forums than it actually has. The games are fantastic (well except Other M) but for some reason it doesn't appeal to that many gamers. Yet the series is often mentioned along side Zelda and Mario as Nintendo's top three franchises when in reality it's topped sales-wise by most of Nintendo's IPs.

So expecting over a million copies sold for a remake released on the dying 3DS was setting the bar really high.

People are very vocal about Metroid and the pedigree of the series, but, when a game comes out, few buy it. Being on the 3DS definitely hurt its sales a lot, too, but the series has never been really big outside of Super and the original Prime. If I were Nintendo, I'd shelf it for a long while again if Prime 4 isn't a big success.

Exactly this! You could either pay $40 for Samus Returns, or play similar and arguably better Metroidvanias for $10 to $15 on another platform. 

Seems like every man and his dog asks for Metroid, but hardly any of them actually buy it.

ive made this predication many months ago and im sticking by it. the 3DS will be dead by E3 2018. there is not a sustainable audience on the platform anymore. you may say "it has over 70 million units sold, how can you say it doesnt have an audience" thats units, not users. at least 40% of all 3DS users own at least two, some even own three. so take that remaining 60% or 42 million and consider that a lot of those remaining units are left to collect dust in used game stores, or thrown in a drawer and havent been touched in over a year. how many active 3DS consoles do you think are left after that? not enough to keep it alive, thats for sure

We want Metroid, we just don't want it on a 240p system weaker than the Wii when the Switch exists.

gonna comment later
