There has been a new edition of the Marauder's Map released recently.
It's a licensed item that will be available later this year at the Comic Con Experience in Brazil.
It's still far from accurate to the original props, but it has some perks to it.
It does include the 'Mooney' spelling in the front of the map.

The print quality also looks way better than any version released previously.

.. and, the best part, it is the first official map to include the new Room of Requirement sections.

I watched a review video earlier today on this map aswell and it does include the 'WW' - JK Rowling's Wizarding World logo on the back.
So it is quite possible this will also be included on one of those mystery boxes they started releasing recently.
