Whenever they lift the embargo, or when the console and game is in your home. If it's different from what the CBOAT said it only means that they changed it at the last second to make him look bad.
Really? If it was in MS power to change the resolution the only possible reason would be to make CBOAT look bad? Not to get to parity with PS4, not to have a more selling points? Solely to make CBOAT look bad? I'm not saying that its not running at 720p and the reason MS/EA haven't said anything is cause they are trying to get it higher, but they aren't doing it to make CBOAT look bad. There are bigger fish to fry.
The embargoes lift on the 12th. This is a few days before the PS4 release date and 10 days before the Xbox one release date. If the new is bad, you'll have time to cancel and start looking for a PS4.
