Paradox is releasing weekly developer diaries so we should get official word on when it might happen sooner rather than later.
Given the rather irregular schedule of Europa Universalis 4's recent updates, it's difficult to approximate when Patch 1.32's release date might occur, but our gut feeling tells us that November/December could be good bets. So when might EU4's patch 1.32 release date occur? We can't pinpoint an exact day just yet but the developer has said that it aims 'to have out later this year.'
