Sony Interactive Entertainment wants to secure their future interwoven to PlayStation. The brand has trademarked PS6, PS7, PS7, PS9 and PS10 in Japan. That’s a logic movement to secure shorts names for future PlayStations.

A regular movement in Sony. For example, they trademarked “PS5” in 2006 and that system is going to be released in 2020.

Brands and legacy.

Thanks, Gematsu.
