My PS3 registration went just fine. it asked me what account to add the pre-order and in game items to (I had 2 service accounts from v1 beta and v1 game purchase). I selected my service and was done. I know it's frustrating but it is a minority of people that are having problems with registration and logging in. I know this because I can log in and play just fine and see all the people camping the same mobs, it's insane in there... not to mention the queue when logging in.
