I think you have mistakenly assumed that sharing his work with the public was not Watterson's absolute least favorite aspect of being a creator. I have no doubt that he is still pursuing creative activities, but I'd be surprised if he decided to share any of it with the world anytime soon. (I figure it will come out either after his death, or once enough decades have passed for him to feel up to facing the public.)
