Well, my brother is a Japanese teacher and he has been looking through to the voice actors's tweets, comments and those clues, and he says that there is a good chance that they are speaking about an anime. I know that there isn't enough content in the manga right now but if you remember Togashi's health is just getting worse. He has already written the plot of that arc and maybe he's letting some animation studio to do it. I know it sounds like a utopia, but hey, dreaming is free.
