Update: Tune in November 9th. The 9th November has now been locked in. As previously mentioned, it seems like this teaser is tied to the system's launch, as it's taking place exactly an hour before the Xbox Series X and Xbox Series S launch (New Zealand time) on 10th November. The same date has been shared on Xbox's Mexico Twitter.
Maybe they have a game to show that's next gen and coming out at launch, only now that would be special
Bet 100% it will be just a luanch type of party for Xbox Series X/S since they will be one of the first to get it over there.
Every time I see ANZ I think of the bank.
