(Pocket-lint) - A patent filed in Brazil by Sony Interactive Entertainment suggests that the forthcoming PlayStation 5 will use cartridges in some form or another.
Either that, or it plans some form of return for games on cartridge or, and this is an even longer shot, smaller-capacity memory cards that work like those released for the original PlayStation in 1994 in Japan and '95 in the US and Europe.
The latter is highly unlikely as we could never see Sony ditching USB ports and external drive support. And, as for game cartridges, Sony's own Mark Cerny has already confirmed that the PS5 will come with a 4K Ultra HD Blu-ray disc drive.
It makes sense. After all, the storage market is huge and, with the PS4 and PS4 Pro allowing you to upgrade capacity using internal and external drives, it stands to reason that this time around Sony wants a slice of that action.
Rather than licence branding to Western Digital or Seagate, it could create its own SSD cartridges and make even more hot moolah itself.
How much they'll cost and where you stick'em are questions for another time.
