Sony Interactive Entertainment filed a bunch of trademarks in Japan with “PS6,” PS7,” “PS8,” “PS9,” and “PS10” for what appears to be a means of securing the names for future PlayStation console names. [Thanks, Gematsu.]
Keep in mind that these trademarks don’t really mean much other than Sony securing them for future use as we’ve seen developers do with certain franchises. The original “PS” was trademarked in 2000, several years after its release in 1994. “PS2” was also trademarked after the console’s 1999 release in 2000.
Sony started filing trademarks earlier with “PS3” which was done in 2005, a year before its 2006 launch, followed by “PS4” in 2006 with a release in 2016, and the latest with “PS5” which was also trademarked in 2006 and it is slated for release in 2020.
