I'll explain this as best I can. I'm a PC player. However I have a PS4. The other day I saw the boxed collectors edition for the PS3 (even though I dont have one) so decided to buy it as the physical items look really nice. Now I hear if you own the Ps3 version you get a free upgrade to the Ps4. So what do I need to do? Can i just use the code I have in my Ps3 version when it comes out on the ps4? Or do i need to install and activate the ps3 version before hand on a friends ps3 under my account? Any advice is appreciated.
