Quick answer: Sony is releasing a Japan-only PlayStation Portal Player in Midnight Black on December 10 for 39,980 yen. It adds internal storage that Sony says is for future functionality, with details to come later.
Sony has a new PlayStation Portal model coming, but only in Japan. On its Japanese PlayStation Blog, Sony Interactive Entertainment announced the PlayStation Portal Player Midnight Black (Japanese language only), launching December 10 for 39,980 yen. Pre-orders open November 13 at 10 AM Japan time at PlayStation retailers and online stores.
The big change is new internal storage. Sony says it added the storage "with an eye towards future functionality" and will share details once they're finalized. It hasn't said how much storage there is or what it will be used for.
Sony is also changing the name from PlayStation Portal Remote Player to PlayStation Portal Player. The reason it gives is that since 2025, the Portal can stream supported PS5 games straight from the cloud with PlayStation Plus Premium, no PS5 needed. This model comes with a one-month PlayStation Plus Premium pass, and it can still use Remote Play with your own PS5.
Otherwise it keeps the same 8-inch 1080p/60fps LCD screen, 3D Audio, haptic feedback and adaptive triggers. It is locked to Japan, though: the system language is Japanese only, and it only works with a PlayStation account whose country/region is set to Japan. So far Sony has only announced this model for Japan.
