Ok so I’m from an area in South East Asia. So, to buy video games here, you have to go through a source, and in most cases the games either arrive early, or they get details not released yet.

When I asked one to see if I can get Pokemon Ultra Sun, what he told me made no sense. But, his details were spot on. Here is my translation of what he had told me. I may have forgotten some bits and for some am not sure what he means by them:

-The game is like the Gold and Metal (what he called Silver) where the game takes over several years after the past ones, but in the same era (I’m at a loss as to what he is saying at the end).
-The Pokemon on the box are not Solgaleo and Lunala, but are Nekrozma it self. In game it will take their light, and take their moves for it self, and after the story an area will open where you can do it too.
-New Zed-Attacks (Z-Moves I assume) for Sogaleo, Lunala, Mimikyu, Luycanroc, Tucannon, Kommo-o, Crabrawler, and the starting monsters in Pokemon Gold and Pokemon White.
-Elite 4 is brand new, run by a masked man looking for an underling. The Elite 4 members help you in the game now. There is a School that is now a tutorial for how to do Trials, and serves as your first Trial too.
-He said a puppy will turn into a gold wolf (I assumed its Lycanroc Duck form). But he also said that there are 4 statues (Island Spirits I assume) that will turn into giant animals to fight back aliens (Ultra Beast).

In all, have a safe night
