I have a feeling (just an opinion, mind you) we still have not seen what Saki is capable of ... I think that we will see her "snap" and go into the peak of her ability before the series runs out - possibly if she plays in the Individuals Tournament directly against Teru. That's a long way off, of course. -_-
Still, Shino is def leveled up here though - and in terms of characters in all of Ritz's works I find Shino to be the most interesting, so it is extra satisfying because of that aspect for me too.
