While Game & Watch: Super Mario Bros. won’t be around forever, it will be distributed for a few months. Nintendo’s website for the system now says that they will “will continue to be shipped to retailers through approximately March 31, 2021, and will be available for purchase while supplies last.”
Those in North America hoping to secure a pre-order might be out of luck, as the official website no longer has a notice about reservations and instead says Game & Watch: Super Mario Bros. will be “releasing November 13th”.
In Europe pre-orders have been open for some time, so importing is an option if that’s something you want to pursue.
