Why ask again when you already asked before? Did you not get an answer? Once the Xbox One releases, you will be able to buy any game digitally from Xbox Live on day 1 of the game's release. So, as Lord Dirt already said above - YES.
...and please don't ask again - learn how to do your own research & find the information for yourself; I hear the Internet is a thing. Trust me, getting other people to do things for you will not earn you any favors.
