Last panel: Marines arriving today.
Narrator: Next day's newspaper is big news.
That's just a slight spoiler from Oda to keep us interested.
Just like chapter 1078 with the narrator telling us that "the outcome will shock the world"
Just like back in Dressrosa with "The Grand Fleet will be part of a big incident in the future".
If Oda were to off screen those event, Marine Ford would never happen on-screen... oh yeah, remember that Oda hinted that with Ace and BB at Banaro Island too.
If the marines weren't present here areiving at Egghead, I would agree with you all... but the chapter literally ends with the Marines arriving (present time).
