Imagine reading or seeing a obito hiden novel!
Explain the main reason he loved rin.
Show him going crazy
show him planning to attack the village
and basically show how his life was after losing rin
training under the famous madara uchiha
All of this was shown in the original manga bar the last part where he trained with Madara.
They already had Akatsuki Hiden and had a good deal of what Tobi did in the original manga as well as the game storylines (an hour special on how they acquired Akatsuki members). What else is there to show bar a fan service story with Team Minato? They're never going to release anything.
LIKE I WOULD RATHER GET MORE DETAILS ABOUT OBITOS LIFE POST RIN DEATH THAN READ A SAKURA HIDEN LOVE B.S STORY.
NARUTOS WEDDING DAY WAS UNNESSASY AND LAME.......AN OBITO HIDEN WOULD OF BEEN EPIC
I would definitely be interested in reading a novel for Obito going over his training, but I still say no.
The purpose of manga/anime these days is to make money, it's a business. A quality story is nice but no longer necessary, the industry is in decline. An Obito novel would not get approved since his name enough isn't good enough to make the pay off worth it. And that aside, he does not have any relevance to the current story like Sakura/Sasuke/Naruto being main characters and parents of the new mains, Shikamaru as Hokage Naruto's advisor, Kakashi as a short-term Hokage, Hinata as the Hokage's wife, etc still do.
Akatsuki and Itachi got novels since the writers and Kishi know that they have a strong fanbase that is willing to buy that merchandise. Obito alone still lacks this in Japan. The same as Madara and pretty much all the other support characters (excluding Akatsuki as a group and Itachi) there bar maybe Deidara/Sasori (the former is too much of a straight-forward character to get a novel, the latter got backstory in the games and anime already so he doesn't need one either).
