It won't be a system seller and the amount of people who pretend to be Metroid fans is orders of magnitude larger than the real fans (who number a couple of million). Nobody shows up to actually buy these games, they just bitch about them online despite playing Silksong (or maybe pretending to play Silksong). This game will be great, probably the best 3D Metroid, seems likely. It will sell... 5 million units which will be still far and away a major success for METROID but not a major success in general.
