Helstrom, Guardians of the Galaxy Vol. 3, and The Marvels, have all yet to be incorporated into the timeline pages for their respective years, which of course makes sense for the two recent films, but seems a bit odd for Helstrom.

Anyway, I've been working on an updated full MCU timeline spreadsheet, and while nearly all items on the spreadsheet have exact approximate dates (yes, I realise the oxymoron), the three items I've mentioned are currently blank in the dates column.

So, I'd very much like to know, what are our best, most exact guesses for the approximate placement of Helstrom, GotG 3, and The Marvels?
