You realize the guy that reported said the information is likely inaccurate or misunderstood right? Even then, the only evidence Smash 6 has was Studio S hiring people to work on a 2.5D sideview action game back in 2023-2024.
That could still end up as something else, maybe a new side mode in Air Riders, Digimon Rumble Arena reboot, or Tales of Versus 2/Remake even.
Sure, they're not Nintendo first party games but it's possible.
