I'm only here to let you guys know that Falcom has never revealed a trailer at a shareholder meeting. I don't expect this one to be any different. We probably won't see Sen III in action until late spring, early summer 2017, if it's a Sept 2017 release.
As a reminder, Sen never got a trailer, and Sen II's trailer came out a little over a month before the launch.
If anything, Falcom will be releasing character art, a screenshot or three, and possibly minimal information on the game. And that's if they're feeling generous. They basically only gave four character designs with the reveal of Sen no Kiseki in 2012, and that's it. They just let people speculate wtf was up with the characters that would end up being Rean, Alisa, Elliot, and Laura. I don't recall any information beyond that starting to come out until Feb or March.
AND as another reminder, it'll be like that this time, too. We'll get the first burst of information now, then we'll wait a couple of months or three before Falcom starts doing anything about what's unveiled at the shareholder meeting. And they will be focusing on Ys VIII PS4 first for their marketing campaign.
