I don't think there is any plot left for a mainstream sequel; not the way they've set the parameters of their stories. As long as they don't go into the personal lives of the characters, which they really haven't, it's just more glares between players at tournaments. A bit like Vol 18. Now that they've milked the Sai/Shuusaku angle dry there's just the normal day to day Go world left.
