Yes, Nintendo Switch 2 Edition games will contain the upgrades on the cartridge, but it seems Breath of the Wild DLC will still need to be purchased separately

• Nintendo has now clarified that Switch 2 Edition cartridges will feature the full game and upgrades
• There’s still some uncertainty regarding DLC
• My Nintendo Store customer service representatives have said Breath of the Wild Switch 2 Edition “will not include the paid DLCs”

Nintendo has confirmed that Nintendo Switch 2 Edition games will contain the full game and upgrades on the cartridge, but there’s still uncertainty surrounding some downloadable content (DLC).
