When it comes to CBM figures, you have to time the announcement close to the release of the film. Going by that logic, Logan should be shown mid February, Guardians should start being shown March to May and into summer because HT aren't as good as coinciding with releases anymore, then by June/July, you'll see a clash of Wonder Woman (probably just her) and Spider-Man, where we'll get just Spidey and Vulture, the latter will be on display at SDCC but will be relased late next year. Also at SDCC, we'll have all the prototypes for these figures as well as possible late additions to the Rogue One line on display, maybe the Trinity from Justice League (November), as well as an early look at Thor from Ragnarok (November too) with an Avengers Hulk added in as a placeholder.
There's also wildcards like Alien Covenant and Blade Runner 2049 thrown in, out in May and October respectively as well, so if they are making something from them, I hope they make Fassbender but it'll probably be just a license announcement, with the only figure previewed at SDCC, up for PO in December, then released in September 2018. For Blade Runner, expect Gosling and Ford only, maybe Leto depending on the marketing and fan response to whoever he plays.
Another thing with the final four months of the year is, yes you have Justice League and Thor 3, but you also have the run up to Star Wars Episode 8. So on Force Friday, expect to see a new Kylo Ren up for PO, troops and maybe a human like Rey too. It's sad but this is the reality of HT now.
