Well, Dragon Ball Fusions is there in the Family section, and it wouldn't be uncommon for a recently released title to show up to maybe get attendees interested in buying the game after the show. Though, Berseria does have a demo available that anyone can download, so I guess there'd be no point in that.
Bandai Namco's western branch usually has its own media releases for TGS, and we'll likely get some sort of English trailer for the game around TGS. (For example, the same happened for Digimon Story: Cyber Sleuth last year. It was out in Japan since February that year, but Bandai Namco America / Europe released a new trailer at TGS.)
