Online multiplayer on PS4 will require a PS Plus subscription, confirmed in the above video produced by Sony demonstrating physical disc game sharing on PS4.

Existing PlayStation Plus members – or even those who sign up from here on out – will find their subscription extended to PS Vita, PS3 and PS4. The PS4 launches Holiday 2013 for $399.
