Nintendo has rolled out a new update for Super Mario Bros. Wonder, bumping the game to version 1.2.0 on both the original Nintendo Switch and Nintendo Switch 2. While the patch itself is light on sweeping changes, it arrives alongside the newly released Nintendo Switch 2 Edition of the game and signals Nintendo’s continued support for one of its most celebrated recent platformers.
What Is Super Mario Bros. Wonder?
Released in October 2023, Super Mario Bros. Wonder marked a genuine turning point for Nintendo’s 2D Mario franchise. After years of New Super Mario Bros. entries that many fans found formulaic, Nintendo EPD took a different approach — keeping the classic side-scrolling platforming intact while injecting the game with a level of creativity and personality that felt genuinely fresh.
The game introduced new power-ups that quickly became fan favorites, most notably the Elephant Fruit, which transforms Mario and his friends into a lumbering elephant capable of smashing through obstacles and spraying water. The Bubble Flower rounded out the new additions, giving players a more versatile tool for dealing with enemies at range. On top of new mechanics, Wonder also brought noticeably more expressive and fluid character animations, pushing the visual style closer to what audiences saw in The Super Mario Bros. Movie — a deliberate choice that gave the game a warmer, more cinematic feel than its predecessors.
The Nintendo Switch 2 Edition and What It Adds
The version 1.2.0 update is closely tied to the launch of Super Mario Bros. Wonder — Nintendo Switch 2 Edition + Meetup in Bellabel Park, which is now available as a paid upgrade priced at $19.99. The upgrade is not included in the update itself — it must be purchased separately. A standalone physical version has also been released for players who did not own the original Switch release.
The Nintendo Switch 2 Edition adds a substantial amount of new content, with the majority of it centered on expanded multiplayer modes. On the single-player side, new Koopaling conflicts have been added, giving solo players fresh challenges to work through. A brand-new power-up joins the roster on top of the ones introduced in the base game, and both Rosalina and Luma are now playable characters — a welcome addition for fans who have wanted to see the duo in a 2D Mario setting.
One of the more surprising additions is a Pikmin crossover. The Nintendo Switch 2 Edition features cameo appearances by Pikmin characters, which fits loosely with the game’s Flower Kingdom setting from a visual design standpoint. It caught a lot of Nintendo fans off guard when it appeared in a recent trailer, but it’s a charming detail that bridges two Nintendo franchises that don’t often share the same space.
The timing of the update and Switch 2 Edition also aligns with The Super Mario Galaxy Movie’s theatrical release on April 1 — a calculated move by Nintendo to maximize Mario’s presence across multiple platforms at once.

Nintendo has published the official patch notes for the update. Here’s everything included, broken down by platform:

It’s a concise update — the kind Nintendo typically uses to lay groundwork ahead of larger content launches rather than deliver headline-grabbing changes on its own.
Looking Ahead for Mario on Switch 2
Super Mario Bros. Wonder continues to be one of Nintendo’s strongest-selling titles, and the Switch 2 Edition is clearly designed to extend that commercial run into the new hardware generation. That said, many Mario fans are looking beyond Wonder toward what comes next. Rumors of a new 3D Mario title built specifically for Nintendo Switch 2 have been circulating for some time, though Nintendo has yet to confirm anything publicly. With the second half of 2026 approaching, an announcement may not be far off.
For those keeping an eye on the broader gaming landscape this year, it’s been a busy stretch across all platforms. Serious Sam: Shatterverse was just revealed as a 5-player co-op roguelite FPS heading to PC, PS5, and Xbox in 2026. And Wuthering Waves is confirmed for Xbox in July 2026 with exclusive Game Pass rewards lined up for subscribers. Between Nintendo’s continued momentum and a packed multiplatform release calendar, 2026 is shaping up to be a strong year for players across every platform.
