I think there's at least one of Later Thor, Earlier DD or Later FF hidden away at the start of Sept.Sure enough the same suspects were back last night with a peak at the Hachette trade catalogue for September and guess what?
Fantastic Four Epic Collection 6: At War With Atlantis
Collecting: Fantastic Four 88-104, Annual 7 and Fantastic Four: The Lost AdventureThor Epic Collection 19: The Thor WarFF now has six consecutive volumes and is the first title to have two consecutive earlier volumes in the same year: Avengers did two later volumes in 2019 and X-Men is set to repeat the feat with 6 Proteus and 7 Fate of the Phoenix in 2019 too.
Collecting: Thor 437-450, Annuals 16 & 17So I got both titles right even if I didn't get the FF volume right. The Hachette trade catalogue for September video indicates these are the only two Epics for September.Very much as expected.
BUT I later added to 2020 Epic Collections September to December this addendum:
Near Mint Condition have subsequently released a provisional schedule on FB:So how could FF 6 & Thor 19 be the only Epics in Septemeber and Black Panther 3 Panther's Prey, Captain America 10 Monsters And Men and Master Of Kung Fu 5 Traitors To The Crown also be the Epics coming in September?September:

The answer is we'e dealing with two different but connected timescales here.
Comics & trades hit comic shops on a Wednesday, and those are the dates in Previews etc. Comixology gets them the same day.
13 days later they hit book shops, Amazon and the like, via Hachette, Marvel's book distributor.
The dates in the The Hachette trade catalogue for September video are from the Hachette catalogue whose book release dates that month are Tuesdays 1st, 8th, 15th, 22nd & 29th of that month. These books will be found in comic shops 19th & 26th of August and 2nd, 9th & 16th of September respectively.
So I'd take a punt FF & Thor are due in book shops 1st & 8th September, so would have been in comic shops 19th & 25th August. Following that there's a three weeks gap and, subject to plans having changed, we get Black Panther 3 Panther's Prey, Captain America 10 Monsters And Men & Master Of Kung Fu 3 Traitors To The Crown in comic shops 23rd & 30th September which then arrive in book shops via Hachette 6th & 13th October.
Clear? No I thought not, it is confusing!
Comic shop dates on the left, book shop/hachette/amazon dates on the right:
The theory is further backed up by looking at prior releases. FF & Thor were first two weeks of September in book shops last year followed by no Epics for the rest of the month and a glut in October. (First date listed is comic shops, 2nd is book shops 13 days later)
Comic Shops   Book Shops Wednesday Aug 19 = Tuesday Sep 01 Wednesday Aug 26 = Tuesday Sep 08 Wednesday Sep 02 = Tuesday Sep 15 Wednesday Sep 09 = Tuesday Sep 22 Wednesday Sep 16 = Tuesday Sep 29 Wednesday Sep 23 = Tuesday Oct 06 Wednesday Sep 30 = Tuesday Oct 13
Indeed there's a very similar pattern the year before
