Not specifically, it's confusing lol. There's two types of updates:

• Paid "Nintendo Switch 2 Edition" upgrades. For older titles getting these like BotW they're adding in some extra features in addition to the performance enhancement. Like they're adding a bunch of Mario Party games that use the camera and such, and a DLC for Kirby. There's also going to be new games released in two versions, one for Switch and one for Switch 2, that will just be the performance upgrades. If you don't pay more, you don't get better performance.

• There's a few games getting free updates that improve the performance on the Switch 2. These are different games than the ones getting Switch 2 editions.

It's complex but in a very Nintendo way, in that they smooth over making you feel like you're getting screwed. Like you'll feel screwed but still buy it? Like the least interesting "Nintendo Switch 2 Edition" is the ones for BotW and Tears, so they're bundling that with the upgraded online subscription a lot of people already have.

Whatever it is what it is.
