Maybe it'll have the premise of the exorcist, after dispatching the original case based upon Blatty's novel, going out in the world and helping others so afflicted. In 2002, there was the made-for-TV version of Carrie (to me, the best cinematic version of King's novel, closest to it, save for the ending) that was to be a pilot for a series where she, in disguise, travels the country helping kids with preternatural powers. Maybe this is the same thing.
