Ok, so this probably isn't all the movie trailers you'll see during the Superb Owl but it's a few of them. The big two holdouts right now are expected new Spider-Man: Homecoming and Guardians of the Galaxy II trailers. It's probably a pretty significant sign as to how confident the studio is in their movies as to whether or not they feel like they need to leak their big trailers early.
There's also a chance we'll see new trailers for Wonder Woman and Thor: Ragnarok and a big big big maybe that we'll see something for Star Wars: The Last Jedi. All three of those movies have been shot and are to be released later this year. None of them probably need the hype machine started this early (with the exception of Wonder Woman, there are a lot of bad rumors surrounding that one) but hey a guy can dream, can't he?
Oh yeah, I can't believe they still make live action Transformers movies. Who watches these? Kids?
