Guys be aware! For early access...

is the preorder code the same as product key from game?

No it is not. After early access you need an official product key or you can't play.

My problem is like I posted in TechSup; after hearing about all the wrong codes and PSN issues and stuff and comfort of us to play I put EA on my laptop but Im a 1.0 user but I played PS3 phase 4 and linked account but I want to know if I lose my minion and hat now.

So I am assuming you don't have access to the ps3 version? I guess that makes sense because how can they give you access to a client you are not supposed to have (I know you have it from beta but I assume they are thinking in general. If someone without the ps3 client asks for a pc code, why would they give that person access to the ps3 version if he has no ability to get access to the ps3 client.)

Also no you still get your items. The moment you put the pc early access, the preorder items got bound to your service account.
