I've pre-ordered BF4 for PS3 and got the China Rising expansion pack. But when I will buy a PS4 with BF4 will I get the china rising pack?
I do believe that EVERYTHING transfers over with the upgrade to next gen.
As long as you preordered the PS4 version, I think you will be safe....but not sure about if you didn't. That's a really good question...
The purchase is linked to your PSN account. You will obviously have to pay the $10 upgrade to PS4 fee, but the pack is still linked to the account and will download based on the system.
I think that as long as you put in the code it will transfer over to next gen. Thats what I am hoping happens. I guess we will have wait and see. If you get premium you wont have to worry about it.
