It's not unusual for the video game industry's big names - Microsoft, Sony, and Nintendo - to plan their lineup of games well ahead of release.
Microsoft, for example, already has a tentative release schedule throughout the rest of 2021 and for most of 2022, as per their announcement at E3 2021.
However, unlike Microsoft, whose games lineup are mostly new IPs that fans have no idea what to make of, both Sony and Nintendo often keep their future games close to the chest, as most are either spin-offs or sequels to well-established franchises.
In the case of Nintendo, it's a sure bet that it will always have a new game based on either Mario, Pokemon, and The Legend of Zelda.
Now, it appears that an industry insider has leaked information for the Japanese company's 2022 games lineup that would include new entries on all three of its big franchises, among many others.
