The Switch 2 is going to absolutely shred the market, but it won't be because of potential vaporware Prime 4 lol.
Sure, I have no doubt it would do crazy better than last games in the series just like Pikmin 4 did, and it's one of the few first party Nintendo games that I'm still excited for, but there's a reason they don't make many Metroid games anymore.
