We're excited to announce that we've fully migrated the Xbox Forums to their new home, here on the Microsoft Community forums!
As of today, going to forums.xbox.com will redirect you here to the Xbox area of the Community forums. We've moved all of your existing threads over so you can continue and start conversations with the new forums experience.
We sincerely appreciate the feedback you have provided over this transition and can't wait for you to check out the new Xbox Forums!
Day One was referring to Day One of the console, not the game. Given that launch day was November 22nd and today is April 2nd, I don't think we'll be seeing anything with Day One written on it for quite some time yet.
