Exception being the early access code. You need to pre-order an actual PS4 version to begin playing on the 11th.
My Amazon pre-order will be canceled promptly on March 11. 😇
Actually, if people transfer the license from PS3 to PS4 they can start playing on the 11th.
If you own one collector's edition, you get all the pre-order bonuses. Regardless of which system you have the game on, and regardless if you do the free transfer or not.
You do not need to do anything. The bonuses will be yours on release day.
You're sure? He's asking about pre order bonuses (Caith sith doll, moogle cap), not CE items. If you don't have the preoder bonuses on the PS3, I don't think you'll get them for the PS4 automatically.
