Well, it might be harder for him since Hanyu is practicing 4 loop, even 4 axel... and so do other youngsters. Of course they are still inconsistent but at this rate, I think PChan should have a new quad before Hanyu perfect his 4S and 4 loop next season.
He'd better come back right away next season. Because if the skips a season, the judges might not give him a monstrous PCS anymore.
I think there is possiblity that he will come back for nationals, because it is almost 100 % that he will WIN it. I think he will continue after that if he will be able to fight for the wins with Hanyu but if not I can't see him competiting since I am finding him as a person that can't accept loosing
