This is the big question, right? Let me give you the honest answer: it depends on you.
What's Actually Different
The Switch 2 is faster, has a bigger and sharper screen, outputs 4K to your TV, and has way more storage. Games load faster and run smoother. The new Joy-Cons snap on magnetically. It's better in basically every measurable way.
But "better" costs $450.
You Should Probably Upgrade If...
You play on TV a lot. The jump from 1080p to 4K HDR is real. If you have a nice TV, you'll notice.
Performance bugs you. Remember how Pokémon Scarlet stuttered everywhere? Or how some games took forever to load? That stuff is mostly fixed on Switch 2.
You play every day. If gaming is a big part of your life, the improvements make everything feel better.
You want GameCube games. Wind Waker, F-Zero GX, and eventually Sunshine and the Pokémon games are Switch 2 exclusive.
You Can Totally Wait If...
You play casually. If you pick up your Switch once a week, your current one works fine.
Money is tight. $450 for the console, then controllers, maybe storage, maybe games. It adds up fast.
You want more exclusives. The first-year lineup is solid but not incredible. The real heavy hitters are still coming.
The Library Thing
Almost all your Switch games work on Switch 2. You're not starting over. And many of them actually run better on the new hardware without any patches.
My Take
If your current Switch still does what you need, there's no shame in waiting. But if you've been frustrated by performance, want better visuals, or you're just ready for new hardware, the Switch 2 delivers.
