Have we heard back from the developers? I know its skeptical thinking, I mean why would they worry about their community members and go on the forums to speak to them.
What are you waiting to hear?
Let me go ahead and spoil the surprise:
"We here at Bethesda are super excited to be working with Microsoft again to bring gamers some cool exclusive content for the newest entry in the Fallout series. Blah, blah, blah."
You're going to get PR speak and nothing resembling an "explanation" because the explanation is that there is absolutely nothing about this situation that benefits consumers.
