A:AnswerWhile you may be able to purchase Xbox Series X in-store with cash after launch, it may not be preordered online with cash. We recommend contacting your local Best Buy store to see if you can preorder in person with cash.
A:AnswerDoubtful since the stores now close at 6pm everyday. Microsoft would have to allow them to release it any earlier than 12am Eastern. The last console release was the Switch, and they made every time zone wait until 12am local time. But that was Nintendo's decision, not Microsoft. If they allow it, it will happen.
A:AnswerUnfortunately, we don't have any information about Microsoft Flight Simulator for Xbox or hardware compatibility at this time. Please keep an eye out for a future announcement!
