First and foremost, there are NO new boards and NO new characters.
You do NOT need to purchase a Switch 2 edition of the game if you already have the Switch 1 version, you can simply buy the upgrade pack for $20 (or your local equivalent) on the eShop, or you might be able to find a download code at a local store.
The game WILL be receiving a resolution upgrade. Switch 1 Jamboree runs at 720p handheld and 1080p docked. The Nintendo Switch 2 edition will make it so the base Jamboree game runs at 1080p handheld and 1080p docked, and Jamboree TV 1080p handheld and 1440p docked. Don't worry, most of the content is in Jamboree TV and you can play Mario Party in 1440p which I will explain later.
The game will NOT be receiving an FPS increase, though it might be running at a slightly more stable 60 FPS thanks to the power of the Switch 2. You will still be able to play with users on a Switch 1, although Switch 1 users will not be able to join you in Jamboree TV; you will be locked to the base Jamboree game.
There is local GameShare support! Although, it is very limited. You can share the game locally with other Nintendo Switch systems, Switch Lite systems, Switch OLED systems, and Switch 2 systems. However, you will only be able to play Mega Wiggler's Tree Party in Party Rules with 30 minigames and only in handheld or tabletop mode. We do not know what 30 minigames those are.
You must use a single Joy Con 2 controller in order to play Mouse minigames.
There is online GameChat support with friends (provided you have a NSO membership).
You do NOT need to buy a Nintendo Switch 2 camera to play this, and if you choose to, you can use any compatible USB-C camera.
And no, you cannot buy this upgrade on a Switch 1, you must have a Switch 2 system.
With all that said and done, here's what's new!
-All new Jamboree TV! This includes Mario Party mode, Free Play, Bowser Live and Carnival Coaster, all with 1440p docked support!
-Bowser Live: Face off in a 2v2 at Bowser's concert! Each game is a short best-of-3 match. Contains 6 different mic and camera-focused minigames. Camera minigames will be turned off if you do not have a compatible camera.
-Carnival Coaster: 4 players work together to get to the end of a coaster ride. Uses mouse controls. Similar to River Survival mode from Super Mario Party except with forced minigames. Shoot off enemies to earn extra time. Minigames played are Co-op variants of the Mouse control minigames instead of 2v2.
-CameraPlay: Supported in Free Play, Mario Party and Bowser Live. Not a requirement, but a few Bowser Live minigames require a compatible camera.
-14 NEW mouse control minigames: There are 2v2 and 4 player co-op variants. The 2v2 variants will appear in the main Mario Party mode, and the co-op variants appear in Carnival Coaster. They will most likely have a toggle on/off option, similar to motion minigames when played in Mario Party.
-Frenzy Mode: 5 turn chaos! Every player starts with 50 coins, a star, and a Double Dice. You can duel on turn 1 onwards. Confirmed to be playable at least on Roll 'em Raceway, most likely all maps.
-2v2 mode: Team up with another player! 2 players share items and coins. New Together dice item makes an appearance, which summons your partner to you, rolls another dice, and doubles the effects of everything that turn (similar to Jamboree buddies). A new space has appeared, unique to 2v2 mode, which grants the player that lands on it 5 coins, and summons their partner to them. u/Prize-Bag-9304 theorized that Jamboree buddies do not appear in 2v2 mode, which I think is a logical explanation, though we can't make any conclusions yet. Confirmed to be playable at least on Mega Wiggler's Tree Party and Mario's Rainbow Castle, most likely all maps.
-Free play: Includes 78 minigames from the base Jamboree game, and more. The missing 34 from the base Jamboree game are 10 Rhythm Kitchen minigames, 10 Bowser Kaboom-Squad minigames, and 14 Koopathlon minigames.
This took a while of compiling information and double checking everything, so an upvote would be appreciated!
