But yeah, reevaluating, it will probably sell okay. Won't be Mario Odyssey levels of sales, but won't be Fire Emblem Warriors levels of sales either.

How could you know that? Those games had tons of attention well before the scores came out. Obviously good scores help, but I wouldn't say they matter that much.

They should have bundled it with a switch with two pink joy cons. That would have pushed out plenty copies of the game.

I don't think it'll flop, Kirby seems to be a series that always does pretty well.

Considering that Kirby is one of the most successful franchises of all time, and that MOST Kirby games, but especially traditional Kirby platformers, have pretty much ALWAYS sold 1 million+ copies on every console, the OPs prediction is one based on personal bias, not facts.

Kirby will sell probably 1,5-2 mln LTE.

Nintendo needs to start focusing on 3D platformers. Odyssey is about to blow the roof off of any previous 3d platfortmer in sales and I think shows that even the more casual audiences are ready to get behind 3d platformers as 2d ones are becoming very tired. Nintendo has given us enough 2d platformers in the last decade to have a surplus for years, it's time for a major 3d platformer resurgence as that's where most of the untapped potential in the platformer genre is and I think people are ready to embrace them more than 2d ones. I've been hoping since it's been ages now since we've seen or heard anything on Yoshi that maybe it's being revamped as a 3d platformer. 

No, thanks, I want my ration of 2D platformers. Why not both? 3D doesn't make a game automatically better.

It's unlikely Kirby won't hit 1M, even with a lower than average score

Is it the biggest release since Xenoblade Chronicles? After that is Mario Tennis in June, right?
