Like the title says, I was wondering if there's any information on when the next three updates after Forsaken Shores comes out. If Forsaken Shores releases in September, then there are three months after that (October, November, December). Considering that as time goes on the content update gets larger to where it takes up three weeks (at least in Cursed Sails) then it is safe to assume Forsaken Shores, and all other content updates after it, will take a minimum of three weeks.
So, if Forsaken Shores comes out on September 25th, and it runs for three weeks, it will go until October 16th. If the next three content updates were to have one bilge rat adventure between them, then no content updates would be released in October, one would be released in November, and two would be released in December.
Now, because it would be a nice balance for a content update each month, this has lead me to believe there will be no Bilge Rat Adventures between the next major content updates, starting after Forsaken Shores.
Tl;Dr
Content updates after Forsaken Shores will be back-to-back because there isn't enough space for Bilge Rat Adventures.
