'Tokyo Ghoul' season 3 release date, updates: Did production already start? Will studio stick to source material?

It has been a while now since new episodes were released for "Tokyo Ghoul" and there are speculations that Pierrot has already started the production for the third season. Hopefully, this time, they will not stray from the source material.
During the first installment of "Tokyo Ghoul," fans were pleased with the outcome since the studio, Pierrot, followed the storyline of the manga series. However, the second season made some fans disappointed when they deviated from the plot arcs that were shown in the comics.
Many fans are hoping that what happened during the show's second season will not happen to its third installment. There are speculations that the production for the next season is taking its time so that the network would have more space to focus on its storyline.
During the finale of the anime's previous season, Ken Kaneki is thought to have died in his battle with Arima. Meanwhile, in the manga series, he was supposed to survive and have a new identity in order to escape the clutches of the Aogiri Tree. Instead, it is rumored that the main character will still be alive in the third season, but he will have amnesia. Then he will take on the role of being the leader of the CCG and his new name will be Haise Sasaki.
Many fans are also requesting that the studio stick with the source material of "Tokyo Ghoul" so it would not compromise the future storylines that will be written for the manga series. While the first two seasons already offered bloody scenes, it is predicted that the upcoming season will feature more brutal sequences.
There are speculations that in the third installment, Arima will help Ken Kaneki in regaining his memory, but the two characters will eventually have an intense battle. This would lead to Arima committing suicide in front of the main protagonist, and this brutal scene may be incorporated in the upcoming season.
There are no official announcements yet for the premiere of the third season of "Tokyo Ghoul," but many fans are hoping that the production may have already started.
