(adsbygoogle = window.adsbygoogle || []).push({}); I have just got BF4 for PS4, but i have just like nothing. If I start playing it on PS3, can i get lot of items, and then get them transfered to my PS4 BF4 account? I'm using the same PSN login.

yes they say that bf4 stats transfer over, but just like other games that transfer, u can only transfer stats 1 time

So if i've already loaded it to PS4 it's just bad luck?

BUMP.

Will my stats on PS4 update, if I start playing BF4 on PS3 and get a lot of stuff and so?

PS3 to PS4 - Your stats will transfer ONE TIME. After you transfer them once, then you may not transfer them again and you're stuck with them.
You can unlock everything on PS3 and then transfer the stats to PS4 ONLY IF THE ACCOUNT HASN'T BEEN TRANSFERRED already.
If you have your account on PS4 they will not continue to update on PS3 if you have previously transferred. Vise versa with PS3 to PS4
