Sony Interactive Entertainment clearly believes the power of PlayStation isn't waning as it files trademarks for no less than five future consoles.
Trademark applications have been submitted for PS6, PS7, PS8, PS9 and PS10 in Japan, Gematsu reports.
Naturally, this is not confirmation any of these machines will exist. Instead, it's likely trademark security to prevent anyone else snapping up these brands before PlayStation.
In fact, Sony has a history of future-proofing its console strategy this way. In 2006, the same year the PlayStation 3 was released, the platform holder trademarked both PlayStation 4 and 5 -- which is amusing when you consider the company refused to call it that until earlier this month.
