Testing within the Microsoft network is an ok place to start testing, but does NOT constitute testing. Testing must include testing as users would see it, and Asobo/Microsoft MUST build and create test plans on PC’s and Xboxes on a non-Microsoft network before they can consider their testing regimen complete.
This could be a major issue in their test plan if they’re not already doing it. I have a hard time believing they’re not already doing this?
