I know that online for PS4 will be a paid service but will you be able to use your PS3 online name on PS4 by signing in with the current account details? Can you help because f you can but will loose everything then i wont bother signing up on PS4
I think you will be required to use your PS3 login on PS4. Since all your information like trophies and games are linked to your account, you probably won't lose anything/much when you switch over.
Now that is good news, and thanks for being the only one who cared to answer
