This market will resolve to YES if Nintendo's next generation system is revealed by Nintendo before January 31st, 2025 at 11:59PM PST.

A reveal will be defined as a major announcement that shows official imagery or render of the new system and an official name. Anything remotely resembling 

 would qualify, but something such as a social media posting showing a visual of the system and its name would resolve to YES as well.

There are other markets covering this, but this market serves the purpose of a higher liquidity YES/NO.
