well, I'm glad he quit Xfactor now , imho after 3 seasons he wasn't as interesting as at the beginning in that role (for me, he could have quitted after the first year, but since he didn't finish the album until 2015, it was a way to keep Italian audience interest live and have a payoff) and I'm happy if he experiences something new, tours other parts of the world or focuses on new music
I would add that I'm happy he earned a lot of new fans in Italy during these 3 years ,I joined this fandom when TOOL came out and he hadn't a really big Italian fanbase in that period, a lot of them may have discovered him thanks to Xfactor but then they fell in love with his music and started to go to his shows, so, I hope he won't lose a significant part of his Italian audience when he won't be every week on tv or every day in some random tv commercial
