A digital preorder feature may be out in a few months time, according to coments by community manager for Sunset Overdrive Brandon Winfrey.
Speaking in a community update, he said that Xbox One owners would soon be able to pre-order their game digitally.
“Yes, if you preorder the game digitally, you will get the Day One Edition content. You can’t preorder it digitally yet, but soon you will be able to.”
Given that Sunset Overdrive is set to release October 28, it appears that the pre-order system will roll out before then.
