Imagine if due to internal conflict they cannot get the IP sequels out so instead they retouch their older base games with new content and fix broken stuff along the way: IE: Room 10 of Master Sword Trials and frame rate fixes in certain areas and random glitches: Maybe add a new mechanic or two/more armor, special weapons that can be fixed easily like the champion weapons that require materials,etc.
IE: There's a nasty glitch where randomly in the Master Sword Trials it will force quit saying 'your cartridge has been removed' forcing you to start over if you do it over again already once and went back to a previous save by the sword itself. This glitch DOES NOT occur if the save file is elsewhere only if you saved just before the trials and reload it two or three times:
Imagine if Mario Odyessey gets extra levels and/or costumes,etc similar to the Mario Kart new stuff: What would YOU like to see in existing games if they do this concept to play it safe? I'd love to hear from you the player!
there doesn't seem to be anything here
