This doesn't answer my question at all but thanks a lot.
Fees by account ok- then if i prepaid for my gametime (like 60 days) then i can use this time AT ALL my platforms? I have copy for ps4 and ps3 so for one fee i can play everywhere? What about 30 day trail, it work the same? If i activate 30 day trial at the end of month can i play 5 days on ps3 and then trasfer to ps4 and play 25 days?

The most important is - how many copies (or cd keys) i need to play with my wife on ps4 and ps3 and if we want to change consoles (one day im on ps4, the next im on ps3 and my wife on ps4).
Thanks
