No, it won't. Kevin Smith already revealed some time ago during a convention that it would focus on Teela instead of He-Man, and it's more about her adventures than his. He later made a post (or someone did) after some backlash and clarified that it was still going to be about He-Man, but the cat was already out of the bag because he was on camera reading the description. And the description clearly sounded like He-Man would be a secondary character in his own story next to Teela.
