I don't know who David Detweiler is specifically in this context. He could be the author who is sharing his personal experiences or fictional stories related to New York.
Not necessarily. While popular manga can increase the chances of an anime adaptation, other factors like studio decisions and market trends also play a role.
I'm sorry, I don't have information regarding the release date of his new novel. You could check his official website or major book retailers for the most accurate information.
Sure. High manga sales can mean there's a big demand for an anime version. Studios might be more likely to make it and put in more resources for a better result. Also, good manga sales can generate buzz and attract more viewers to the anime.
New Edition was a very popular group. If Josh David was part of it, perhaps his story involves the early days of the group's formation. He might have been involved in the auditions or the creative process in the beginning. It could also be that he had a role in the group's management or was a friend who influenced their music in some way. However, without more information, it's hard to tell his exact story.
I'm not sure which ones are the most anticipated at the moment. But his past works have been so popular that any new release is likely to be highly anticipated by his fans.
