Seth Mitchell the next Mike Tyson?

No way. He lacks Tyson's upper body head movement, which helped Tyson defensively and made a way for him to get inside on taller opponents. He also doesn't have an elite trainer like young Tyson had. He also lack the ferocity in his approach. Also, as far as him becoming world champion...there's this thing called Wladimir Klitschko in the way. Cant see Mitchell beating him. I agree with all you said about Mitchell's positives and he has a good promoter, so he will get a shot someday.
