There might be one in September still. While Heiji likes to post about every single issue, for the past five years Berserk has only been published in issues with odd numbers (1, 3, 5, 7...).
It had been officially announced at the time that it would only be published once a month at most going forward.
So I can tell you for sure that Berserk will not be featured in Young Animal #20 (published October 9), Young Animal #22 (November 13) or Young Animal #24 (December 11).
When Berserk might be published is in YA #19 (September 25), #21 (October 23) or #23 (November 27).
