No formal announcement yet, but Afreeca updated their esports portal page with the above poster. Hopefully they'll confirm with the timeline for the qualifiers soon.
Glad to see Afreeca following through with the December timeline as mentioned at the finals of the first ASL. December 4 through January 22 is pretty similar to last season -- assuming only Ro16 again.
