Pokemon Winds and Waves and 3D Mario: 2027 Release Months Leak

If you’re deciding whether to keep waiting for Gen 10 Pokémon or a new 3D Mario, a fresh leak claims Nintendo’s 2027 slate could finally line up: Pokemon Winds and Waves reportedly targets September 2027, with a new 3D Super Mario game following in November. Here’s what’s known from the leak, what it builds on, and why timing matters for both franchises.

What the leak says has changed for both franchises

A prominent leak aggregator, Centro Leaks, shared a post claiming a specific internal plan for two major first-party releases. The report ties Pokemon Winds and Waves to a September 2027 launch month, while placing a new 3D Super Mario game in November 2027.

The source behind the claims is described as “Billy,” an anonymous but previously reliable leaker who has reportedly shared broader lists of titles and reveals tied to Pokemon Day 2026. The September/November split also aligns with an earlier rumor suggesting Pokemon Winds and Waves would land in late 2027 rather than having an announced window at the time of its reveal.

For context, Pokemon Winds and Waves was formally shown during the Pokemon Direct held on Pokemon Day this year, February 27. At that reveal, the games were confirmed for 2027, but no specific release window was provided. Separately, while fans hoped to see a new 3D Super Mario release during this year’s Nintendo schedule, nothing was officially announced—making any month-specific guidance particularly notable.

Who should care: Gen 10 timing and the long 3D Mario gap

The claimed 2027 timing will be a mixed bag for Pokémon fans. Some players may welcome the extra runway after the highly scrutinized launch of Pokemon Scarlet and Violet, while others will be disappointed by the delay—especially those expecting Gen 10 to arrive sooner.

The source frames the gap as roughly five years between Gen 9 and the next mainline generation, which naturally increases expectations around what Gen 10 could deliver. That long lead time is part of why the hype is described as “massive.”

Super Mario fans, however, are dealing with an even longer wait. According to the source, there has been no new 3D Super Mario game since Super Mario Odyssey in 2017. A November 2027 target would therefore land as the next chapter in the 3D series after a decade-long stretch with only earlier entries and spin-offs.

The leak also notes that these months fit a familiar Nintendo rhythm: major Pokémon releases often land around the holiday season. It further suggests an internal calendar logic where Pokémon could launch in September, potentially followed by December content, while November would be reserved for the next 3D Mario release.

What comes next and how confident you should be

The leak’s timing narrative is reinforced by what didn’t happen in recent messaging. The source points out that Pokemon Winds and Waves reportedly did not appear during a recent Nintendo Direct, and that other Pokémon DLC details were said to be the final content planned for the year. Together, those omissions are presented as evidence that Gen 10 could be arriving late in 2027.

Still, the article stresses that leaks should be treated cautiously. Even with a track record attributed to Billy, release months can shift as development progresses. The source also notes that it could be a few months—or longer—before Nintendo formally reveals more about the next 3D Mario game.

Timing-wise, the leak adds one more reason the months may be plausible: the source highlights that Super Mario Odyssey reaches a 10-year milestone next year, and November 2027 could be an attractive window for a new 3D entry after that anniversary. It also mentions that September 13 is relevant to the Super Mario 40th anniversary date, raising the possibility that Nintendo could use that occasion to preview its 2027 plans.

What players should know

• Pokemon Winds and Waves is already confirmed for 2027, but this leak claims September 2027 specifically.
• A new 3D Super Mario game is also claimed to be targeting November 2027.
• The leak is attributed to a previously successful leaker (Billy), but the source still recommends treating details as unconfirmed.
• If the months hold, Pokémon and Mario would effectively bookend the 2027 holiday build-up: Pokémon in early fall, Mario in late fall.

Expert View

If you’re looking for a practical takeaway, the most useful part of the leak isn’t just the year—it’s the proposed split between Pokémon in September and a 3D Mario release in November. That sequencing fits how Nintendo has often structured holiday-adjacent launches, and it matches the idea that Gen 10 could be late 2027 after recent absences in Direct coverage. That said, month-specific leaks are inherently fragile, so it’s smart to watch for confirmation closer to the Super Mario anniversary period and the next major Nintendo showcase rather than treating this as final.
