I expect nothing except infos on age 4 which were confirmed. always best practice for E3
I think they may show infos on naval warfare and maybe a bit more about the campaigns.
They WILL show (I think) the updated graphics including smaller arrows but not a total change of art style, and also the 4 missing civs.
They will again tell ppl they can become age insiders to join the beta or maybe be able to join it - “today” as I HOPE they will say, but I assume Beta may start within 1 week afte rthe presentation. If beta doesnt start by then, tbh, there are other games to play
also asides from age 4, I hope to see the age 2 dlc more info^^
