Three days before the controller-image cycle that defined the NX rumor period, Dual Pixels published a smaller item claiming Nintendo was developing a third Luigi’s Mansion for the unreleased NX hardware. The post sourced its information to “industry contacts” and described the working title, an estimated reveal window of E3 2016, and a target launch alongside or shortly after the NX hardware itself.
The post earned 48 backlinks at peak from outlets including GoNintendo, Nintendo Life, Mynintendonews, and the Spanish-language Nintenderos chain. It is one of the more interesting case studies in the NX rumor cycle because, unlike the controller image and the console-spec rumor, this one turned out to be substantially correct — just not in the way the original article framed it.
What actually shipped
Luigi’s Mansion 3 launched on October 31, 2019 — three years after the rumored window, and on the Nintendo Switch rather than the NX-as-described. Development was handled by Next Level Games (a Vancouver-based Nintendo second-party that Nintendo formally acquired in early 2021), the same studio behind Luigi’s Mansion: Dark Moon for the 3DS.
The game sold roughly 13.4 million copies through the end of 2024, making it the highest-selling entry in the series by a wide margin. Critical reception was strong (87 on Metacritic), and the title became a regular fixture of Switch holiday lineups for years.
So a third Luigi’s Mansion on Nintendo’s then-next-generation hardware was real. The rumor was not invented.
What the rumor got wrong
Three things.
First, the timeline. The rumor placed the reveal at E3 2016 and a launch in the NX-launch window (so 2016–2017). The reveal actually came at E3 2019, and the launch followed in late 2019 — a slip of three full years on both ends. By 2017 it was clear that no Luigi’s Mansion 3 announcement was coming alongside the Switch launch lineup, and the rumor’s specifics quietly aged out of relevance until the actual reveal three years later vindicated the broader claim.
Second, the platform name. The rumor used “NX” because that was Nintendo’s then-public codename. The shipping console was branded Switch. This is a vocabulary issue more than a substance issue, but it matters because rumor-cycle posts that use codenames frequently end up overstating the connection between an early-cycle leak and the eventual product.
Third, the development-status implication. “In development” in March 2016 implied a project at a stage that could ship inside 12–18 months. Next Level Games has confirmed in subsequent interviews that Luigi’s Mansion 3 entered serious production after the Switch launch, not before. So even if some early concept work existed in early 2016 (plausible — Next Level Games had finished Metroid Prime: Federation Force by then and would have been moving to a new project), the project as the rumor described it did not exist in 2016.
Why this matters as a rumor-cycle case study
Most discussion of the 2016 NX rumor cycle focuses on the controller image and the console-spec article, both of which were largely wrong. The Luigi’s Mansion item is more useful precisely because it was largely right — and shows how “right” rumors can still be misleading.
The structure of the original post implied imminent reveal and imminent launch. It implied a connection to a specific console-launch window. It implied insider sourcing close enough to the project to know it was in development at a specific stage. None of this was actually established by the post’s evidence.
What was established was the broad structural claim — Nintendo was working on a third Luigi’s Mansion for its next console — which was the kind of thing any reasonably observant analyst could have predicted. Next Level Games’ previous output, the IP’s commercial track record on 3DS, and Nintendo’s evergreen-franchise strategy all pointed in that direction. The rumor dressed an analytical inference as a sourced leak, and got credit for the inference being correct even though the timeline and specifics were wrong.
What hindsight clarifies about Next Level Games
One of the more interesting through-lines of this rumor cycle is what it shows about the studio relationship that produced Luigi’s Mansion 3. Next Level Games was a Canadian second-party studio with a long Nintendo working relationship before its 2021 acquisition. The studio had handled Punch-Out!! for Wii in 2009, Luigi’s Mansion: Dark Moon for 3DS in 2013, and Metroid Prime: Federation Force for 3DS in 2016. The pattern of one Nintendo project per cycle was clear.
An analyst tracking that pattern in March 2016, with Federation Force visibly nearing completion, could have inferred that Next Level Games would be moving to a new Nintendo project. Given the franchise’s trajectory and the sales success of Dark Moon, Luigi’s Mansion 3 was the obvious bet. Whether the Dual Pixels rumor sourced this analytically or via an actual Next Level Games or Nintendo contact has never been established.
The pattern across the NX rumor period
Looking at the three big rumor posts from this period — the controller image, the console specs, and this Luigi’s Mansion item — a pattern emerges. The most “successful” rumor in retrospective scoring (this one) was the most analytically inferable. The least successful (the controller image) involved the strongest claims of insider access. The middle case (the console specs) split the difference, getting the broad form factor right and the implementation details wrong.
This is consistent with how console-leak journalism tends to age. Claims that are easy to make analytically tend to score better in hindsight than claims that depend on hard-to-verify insider access. The narrative incentive in 2016 ran the opposite direction — the controller image got the most coverage because it felt like the strongest evidence of insider sourcing. Hindsight inverts that ranking.
