The feeling of the WG/Kizaru/Saturn/VA currently not being hyped by Oda is because we up until now have seen only the Bonney and Kuma plot-strand, which has now been completed with them leaving the battle in the last chapter. What is now starting is an entirely new plot-strand. And you see it with Oda now focussing more on Vegapunk again - where before, he almost ignored him although he is one of the main protagonists of the arc. This Vegapunk-plot-strand is the actual main plot-strand of the arc. And with Oda now picking it up, he will build tension very slowly around it now.
This also means that the tension needs to come from something. And this something is having it's source in the WG, which is now applying pressure, slowly. You start seeing that by Kizaru mentioning, that he is in "a pickle" now. It implies that he slowly will need to get serious now. Alone his lack of attacks, which pose danger to Luffy and can inflict serious damage to him, has not really been explored by Oda. All this is because Bonney and Kuma's story was needed to be told. With them gone now, Oda will take us to something, the readers will very well remember to be peak, because he is currently hiding so tremendously much, that he even had to put that little time-skip of him in the middle of the arc. Alone this should make us suspicious of what lies ahead.
Just be patient and relax - the WG will show us some moves and wins throughout the arc. It just haven't really started, yet.

By the way - I forgot to mention that Oda even announced a plot-twist in his last Festa-letter. This also should us give pause. And after this, maybe we get to see the 9 VAs against the 9 SHPs. But, who knows...
