By you saying this pretty much going to follow whatever world you go to. Let's say this SE said they only going to had transfer 6-1year from PS3 because they feel that how long it going to take for someone to get bored or want to leave to other world.

Tho they did say this a long time ago still the core system need to be fix first then maybe ps3 need to be out before they even add this but who knows lol.
