It's more on the devs that forgot to disable recordings for GameDVR.
Good point. That's definitely a big oversight on their end, too.
When would a game like this even be released? I feel like it'd be BEFORE Halo 5, not after, as surely MS wants to ride the Halo 5 hype right into the holidays. But at the same time, they'd want to build up hype for this as another thing to sell Xbox Ones... August maybe? Or late December?
