Hey :)

Normally we get codes sent out a few days before launch, if a preload happens we'll make sure you have plenty of time to download. You won't need to worry as we're partnered with Ubisoft and will be able to get keys out ahead of launch.

Hope this helps, also as a note you'll get a Stick of Truth Steam code right away when you pre-order so you won't need to wait until launch for that (Fractured but Whole will be a Uplay code though).
