Still confused:

"Switch 2 Edition Games have the original Switch game and the upgrade pack on the same game card"

Does it run directly from the card, or do you need to install the game which runs the upgrade on top?

Language is hard :/

When I read upgrade pack I assume it needs to upgrade the software, the original Switch game. Or does Nintendo do some magic where it loads the upgrade pack in memory and applies the changes run time while reading the original game code and data from the card?

Following the link doesn't clear it up. It says faster load times as one of the benefits, does that imply the game is installed internally, or that the Switch 2 cards are simply faster (upgrade pack or not).

I'll help clear it up. It means the Switch 2 Editions uses the Switch 2 game cards, not the Switch 1 one. Therefore, you don't have to worry about downloading the Switch 2 upgrade pack if you get the physical copy of the Switch 2 Edition of a game.

As for question of faster loading times, Switch 2 game cards are indeed faster than Switch 1 game cards were.

What should be printed: "Contains the Game and Switch 2 Upgrade Pack on a Switch 2 Game card."

What is printed: "This Nintendo Switch 2 Edition comprises the Nintendo Switch game and the Nintendo Switch 2 Edition upgrade pack."

They used more words and still left room for doubt.

Yeah I got that part. Just curious about the mechanics as upgrade pack sound like a patch (pre-stored on the card) that needs to be applied to the game.

Curious how Nintendo is going to make that work.

Does the upgrade pack simply contain instructions for the Switch 2 on how to interpret the Switch game and alter some of the render parameters in run time?
Or do you need to install the Switch game to internal storage first, apply the upgrade from the card and then play. (Which would all be done automatically on start up, but will take up space on internal storage)

I guess we'll find out at launch. At least Switch 2 has much bigger internal storage.

Some publishers, Square and Capcom come to mind, are just cheap. They pull this kind of thing in the West where they can get away with it. I remember having to import the Asia region version of FFX/X-2 because the Asia region version was on a 32GB card with both games on it. The US version was 16GB Card with FFX on it and you had to download X-2. Capcom was even worse, they had partial downloads for the Megman Collection games which would have fit on 8GB card with ease. Hopefully this trade war nonsense dies down, because I have a feeling I'm going to be leaning on Play Asia a lot more with the Switch 2.

Cyberpunk is $70 on Switch 2, while Walmart currently has Bravely Default up for $40 to pre-order on Switch 2. If anyone releases titles on key cards at $70-$80 they can get gtfo. Though for games that don't fit on a 64gb card that's inevitable.

I can't imagine that this will be any different than later printruns of Switch 1 game cards that had version 1.3 or whatever on them instead of the initial 1.0 version on the first printrun. Meaning that the patches/software updates are already a part of the game card data and are read straight from the card instead of needing to be downloaded to the internal storage.

That's the most logical indeed. First I thought it would be one card for both old and new Switch. But they are Switch 2 cards (which doesn't rule out the current Switch can read them of course)

I guess it's just a translation (non) issue. It's the Switch 2 version on a Switch 2 card for Switch 2.
Just odd the box doesn't simply say "Enhanced version for Switch 2, downloadable upgrade for Switch 1 edition also available separately"

Nintendo and marketing, Wii U vibes lol.

The current Switch wouldn't be able to read Switch 2 cards. While they look the same, they are much faster. It's similar to the situation with the MicroSD Express Cards.
