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!
Ghosts had a cross-buy option when purchased digitally on 360. You could buy the Xbox One version for $10 more. That was only available until the end of March.
BF4's upgrade option was to trade-in the physical 360 version for an Xbox One version at GameStop. That was only valid until Nov 28th.
The lack of upgrade offers isn't much of an issue now. The Standard edition of
Ghosts is $19.99. The Standard edition of
BF4 is $24.99. Combined, you'd be paying less than $45 to get both on Xbox One and you get to keep the 360 version of each.
