The Ultimates sale runs through daily reset on Black Friday (11AM Nov 23 USA ESTime). Small chance the update drops then, but more than likely it will be NOV 27 - 28. In my experience they will do a few more sneak peaks, at least one or two with unis and another one with the T3 announcement. I’ve only see them do an update once during any phase where AC could possibly be active.... So most likely I’m thinking it drops the TUE or WED before DEC.
