Xbox Game Gifting is coming to Insiders today and everyone else soon.
Mike Ybarra just posted about game gifting on Xbox One and it will be available to Preview members today. Everyone else will get it soon.

Features like this are fantastic and I hope the public rollout is soon so I can start gifting stuff to friends. Hopefully Sony and Nintendo follow suit.
