Koneko is most likely going to gain some more Senjutsu techniques, due to her training with Kuroka.

Ravel has to use her powers first, for us to see, what she is actually capable of in combat, before she will gain any upgrades.

the rookie 4

At the current moment, I think that they can easily do this, since they still have a huge gap in terms of experience ... in the rating game ... although given a few years ... I definitely think that might change.

Yes, it has already been implied that Rias power of destruction is different then her brother's.

Although it's still going to take some time for her, to reach it's true potential.

We will most likely see, how powerful her new "move" is during the course of the current arc ... after all, I don't think that the author would have mentioned it, if Rias wouldn't use that move against someone later in this arc.
