Redon said on his forum that the chapter is very text-heavy, explaining in great detail how Shaka, Pythagoras, and Vegapunk discover York's betrayal and the measures they take. There are quite a few more details than what's told in the spoilers (normal, since it's a simplified summary of the chapter) and emotional parts of Vegapunk, as well as some very funny scenes with other characters.
When the full chapter comes out, you'll see that this chapter connects many things from Egghead's arc. It also gives clues about the "legacy" that Vegapunk may have left to the band.
