The Tour should be a certainty for next year, as there is no way that the sponsors will allow Pogačar to skip it because the he is the winner of the last two Tours and they have no alternative in the team to fill his role.
The question is if he races the Giro or the Vuelta as I believe two Grand Tours are on the menu for the next season. I actually think that a part of him wants to ride the Giro already next year as its the only Grand Tour that he never rode and the weather should suit him. However there is a problem called Jumbo Visma.  This year, they may have lost Roglić during the Tour but they found in Vingegård another posible Tour winner for the next years and with the two starting in Danmark, I have little doubt that he will be in the start line next to Roglić.
So this might be the deciding factor that will make Pogačar skip the Giro and go for the Tour-Vuelta double. In the Giro he would certainly be the number one favourite but cycling is always unpredictable and then in the Tour against a fresh Roglić, Vingegård, Bernal and possibily Carapaz it would be unlikely for him to win the race and like Contador he could even be out of the final podium.
The Tour-Vuelta double is not without its dangers, he wouldn't be as favourite for any of those for the Giro but at least he could have a good chance of winning the Tour and in the end that will likely be the deciding factor.
As for this season, I expect to him see finishing the season in the Italian classics with Lombardy as the final goal of the season, maybe with the Worlds in between.
