Rumor: Mario’s 40th Anniversary Could Bring a New Super Mario Bros. Collection Leaked internal docs suggest Nintendo may launch a compilation of NSMB DS, Wii, and 3DS games on Switch 2 around March 2026

A new rumor claims Nintendo is readying a New Super Mario Bros. Collection to celebrate Mario’s 40th anniversary in March 2026—exclusively for Switch 2. The leaker reportedly reviewed internal QA documents and localization assets before sharing the info online.

🎮 Games Allegedly Included

• New Super Mario Bros. (Nintendo DS)
• New Super Mario Bros. Wii
• New Super Mario Bros. 2 (Nintendo 3DS)

These are the only mainline NSMB entries not yet available on modern systems, making them logical choices for a compilation pack.

🤔 Credibility & Context

• Similar to Super Mario 3D All-Stars, released for Mario’s 35th anniversary, precedent exists for collections timed around milestone anniversaries.
• No official confirmation from Nintendo yet, and speculation remains high due to the absence of other major Mario titles in the announced lineup.

⚠️ Community Skepticism & Concerns

• Some fans question why Nintendo wouldn't include other popular titles like Mario 3D Land or Galaxy 2.
• Resurfaced criticism over the limited-time availability of past anniversary collections—fans hope this one remains permanently available.
• Nintendo’s prior practice of “expiring” anniversary releases left fans frustrated about preservation and accessibility.

✅ TL;DR

• Rumor suggests Nintendo plans a New Super Mario Bros. Collection for Switch 2, including DS, Wii, and 3DS titles.
• Targets March 2026 launch to coincide with Mario’s 40th franchise milestone.
• Fans hope this isn’t timed/later removed like previous Mario anniversary collections; full legacy support remains a concern.
