So the latest interview is the final nail in the coffin for Battle Frontier in USUM isnt it?

"The Festival Plaza is an important part of the world we created, so it is still there. However, we added some functionalities like Alola Photo Club, where you can take photos and save them and/or share them with other players. The basis for this is Festival Plaza. There is also another new addition in this area, but we can't talk about it at the moment. We can only say it's related to the battle system of previous games."

I have no idea how this will work but knowing GF and Festival Plaza it will suck ass
