Newbie editor, so I have no hopes.
If he really wanted to leave his mark on the industry, he'd show himself firm in his opinions and try to push Oda a bit, either in being more concise with the storytelling or in finally prioritising lore over gags.
But, like I said, the new guy's young age and overall inexperience with the job, coupled with Japan's cultural subservience to one's seniors doesn't bode well from where I see it.
Plus, given Oda's success, I almost expect him to have carte blance to who mediates between him and Shueisha, i.e. if he doesn't like your ass, he has you changed/fired.
