One thing to point out is that the last time that Shinji did a panel like this was PGW 2016 (which also was NOT livestreamed) and we got 1.5+2.5 announced, Sora revealed in WoFF, and the reveal of the 0.2 opening cinematic.
Am I saying we're going to get news of that caliber here? Not at all. But the lack of a livestream just means it'll be up on Twitter a few minutes after it's announced at the event, IF anything big is announced or shown. Personally, I would set expectations low. This event is giving off more of a celebration of KH3's upcoming release and discussing the game rather than being an event to reveal new information.
I do believe KH3 was recently confirmed to be present at the upcoming Xbox Event happening in Mexico next weekend as well. If they want another slice of hype pie like they were given for E3 2018, they could reveal some news there as well.
