Yeah. It seems we are talking about different things. 😀
Just some background, Nintendo is releasing "Switch 2 enhanced edition" of some Switch games, and there was confusion whether these games will have all data on the cartridge or will only have Switch 1 version, with Switch 2 update as download. So, this clarifies that this is not the case, and the physical versions will have full games available on cartridge.
No worries. There is so much nonsense drama with so many things these days, it takes real effort to understand what's happening with most stuff. Most of the times it isn't even worth it 😀
They shouldn't, but since the game has been enhanced, there's a good chance that something will go a little wrong and need a patch. I would actually guess that most of them end up with a patch, but only a few end up with game-breaking bugs and need a patch.
