I can believe that F Zero, Paper Mario and even Kid Icarus Uprising remasters are real, but I also feel like re-releases are some of the easiest things for Nintendo to move around as schedule filler. Personally I feel like they're better off in the first half of 2024, to plug any gaps in Switch's last year as the sole system, rather than later this year.
If Nintendo are following the usual structure, they'll likely have something Mario in October, something popular ahead of Black Friday in November, and something else in September. A small release might follow at the start of December. I can see August being blank. With mainline Pokemon absent, maybe 2D Mario goes to November, with something from NdCube or Detective Pikachu getting October.
