He's one to watch for sure. But there have been so many up-and-comers in recent years that failed to depose the King: Vinales, Zarco, etc., I won't hold my breath.
We are truly living in the Marquez Era.
I remember in the Rossi years, he would stalk the leader the entire race and just overtake him in the last lap like it was an afterthought. Remind you of anyone lately? MM93 is like a cat playing with its food.
Zarco on a satellite Tech 3 Yamaha was not really a title contender, he gave him a few last lap battles for podium position, but never really had the upgrades on his bike to be taken serious as a contender. If he had a factory seat alongside Mav... well that would be a different story. Mav still can be a contender, but if its between Mav or Fabio, I just have to give it Fabio doing the business.
He was on a limited rev and outdated bike almost all season and still performed, also he got the taste of several victories stolen from him... I think Mav is a lot like Lorenzo, not thier riding styles of course, in that when the bike is not 100% to their liking expect a P3 position at best and don't be surprised if top 10 position isn't possible in the worst case scenario. Much like Lorenzo's last year a Yamaha, really.
Either way, that feeling he gets from Fabio is from the Man himself; Marc doesn't see Dovi as the threat anymore, I personally never thought he was, and his eyes are fixed on a hungry kid on a satellite Yamaha that rides like JLO putting Rossi and Mav in their place nearly every race weekend.
Will he do it next year, probably not unless he gets a works seat at Yamaha where he can have say on the development of the bike. But this could shake out a lot of things over at Yamaha. I'd love to see Mir and Fabio on the Works Yamaha team, Mav and Rins at Suzuki, Marc and Zarco at HRC and Petrux and JLO at Ducati and Miller on a factory supported Pramac. That would be the ideal situation for a proper 8-way battle. Add Taka and Suzuki on HRC backed machinery at LCR for that extra punchy off line excitement and we would have the best season yet, I think.
Dovi, Cal and Rossi are just filler at this point. They had their time, its time for them to move on to test roles, commentary or Team management.
