How will I receive my Pre Order key ?

It's very usual a pre-order doesn't make available the activation key at the moment of pre ordering. The key usually is available on the release date or a couple of days before releasing in order to grant access to preload.

The pre-order key is different from a regular key, so even though it is activated after the release, any bonus offered during the pre-order will safely be released as soon as the key is activated. So do not worry! You will not lose any pre order bonus. ;)
