Will go into the latest Unreal Engine features (
UE5.4 and other forward-looking projects), talk about the UEFN/Fortnite Creative user-generated game feature, probably have some updates about TSR, and will show some stuff they're working on for its game engine internally and with other game developers.
Epic usually don't "announce" games here. (Not that Epic has produced many games since Fortnite anyway...) So don't count on seeing any new games you will be able to buy.
There is, though, typically a wow-factor feature demo of the latest Unreal Engine features that even normal gamers often find cool.
(EDIT: well, nm about not seeing any new games, they just announced Marvel 1943 there and showed a bit of its tech.)
