Nothing yet from Wolfwood re Young being scheduled, so...
The final scheduling of possible cases to be heard in Hawaii by the Ninth Circuit is for October 10-13, 2017. The next possible scheduling would likely be in February 2018, if the scheduling repeats the patterns of 2016 and 2017 (Honolulu scheduled in February, June, and October).

http://www.ca9.uscourts.gov/calendar/)
seems to be working is that each Monday the calendar is updated with the locations/cases/times approximately 10 weeks in the future. Since last Monday they listed the cases to be heard in the first week of October, I'm wildly guessing that they will next Monday list the cases to be heard the second week of October (which would be the Honolulu scheduled sessions). So maybe we'll know next Monday if Young will be heard in Hawaii at that time.
If not scheduled in the October 10-13 window, and the court wants to accommodate the Hawaii County/state attorneys who apparently don't want to go to the mainland to defend their laws, it would likely be scheduled for February 2018 window. It's also possible that the court could hold the hearings on the mainland, either with or without holding the simultaneous hearing for Nichols, and the Hawaii County/state attorneys would then have the choice to either show up or not. There's no rule that requires them to be present and make and/or respond to oral arguments.
