Why the Автор don't Показать 10 years later Tsuna's face in both Аниме and manga?

Maybe because they want to have something that can make the Фаны look вперед for it. I want to see it too :D

maybe they want to make an arc where they Показать future tsuna lead the other in a final battle. they might even Показать future natsu!!!

maybe they will have tsuna hit with the ten год bazuka and the older him will do stuff in the past

Because mystery makes a good character, kora!

Well, there's this

Well Ты already know the answer
They wont let it see because the old tsuna is hard to be
edited dont Ты know how to Редактировать and old или new picture like them?
