I came here the second I saw the news. I guess that Fox cameo in the Mario Galaxy movie had a purpose after all.
I feel like most others probably do: Star Fox 64 again? Even Star Fox Zero felt like a partial retelling of SF64. (It's weird to think Star Fox 64 3DS was back in 2011.)
I think it's good that Star Fox still has relevance for Nintendo in 2026. Even if it's "just Star Fox 64 again," it's more Star Fox content. I played through Star Fox 64 a ton of times in my childhood, so I do have a certain fondness for the franchise.
TL;DR: We may never advance beyond the Star Fox 64 storyline, but at least the franchise isn't in hibernation for a moment.
EDIT: I know I didn't finish Star Fox Adventure, but I don't remember if I ever completed Star Fox Assault. Do either of those take place after 64?
