The pre-release times are over, now it's time to talk post-release! Just keep it as spoiler-free as possible.
As for me, I've put a few hours into the game and am liking it a lot. Just opened up the 3rd area. It's fun to see all the creatures rendered in a modern way, after having just played the original in the last week. It feels so much more lush and alive than Metroid II (as you would expect), and far less confusing. Not even just because of the map, but because everything doesn't look the same everywhere. And the music is much better (although Metroid II had a couple of good tracks on it). Much more Prime-esque, both in music and sound effects that other handheld Metroids. I recommend headphones!
Would this have been amazing on Switch? Sure. But on 3DS, it still looks amazing. One of the few games these days that I make sure that the 3D is on for all the time, since the backgrounds are like little living dioramas that are really cool in 3D. I almost wish I had gotten that Samus New 3DS XL, but I'm too pragmatic to buy a new one when my current one works fine.
My new amiibo won't be here until Tuesday, but I scanned my two Smash ones to get my free energy reserve tank and free missile reserve tank.
Haven't opened my CD yet, but that'll come soon enough. Pity it's not the OST for the actual game, I'll still have to hunt that down.
