New legendary needed badly

Im curious about the timeline....so October is the start of the second half of the year for EA/CG. And I believe they stated we'd get a 2 week notice for any new legendary event (I could be mistaken and that might just be for heroes journey). But anyway that would mean either an announcement/reveal around Sept 17th if an event were to start Oct 1 or would it be an announcement on Oct 1 and an event to take place Oct 15th...
The full solo squad dropped first so I figured it'd be easy to get 5 of them to 6 almost 7* by mid October... for bounty hunters just Bossk has dropped and the other 2 still in packs...kotor will probably start dropping into farms this week though their cadence is kinda messed up with T3's weird release
