Next Fiddle and Voli update?

I forget which post it was on, but I saw Reaves mention the release plan was Senna -> new marksman (Aphelios) -> new juggernaut (Sett) -> Fiddle -> Voli. Now that Sett is revealed and on the PBE the reworks should be next, but on the last roadmap he stated there would be another update on the 2 beforehand. So is it getting dropped later this month or is it gonna wait until January?
