User blog comment:Kaido King of the Beasts/Cover Mini-Review: Solo Journey of Jinbe, Knight of the Sea/@comment-24850639-20150520175752

For the most part it's been said, Wadatsumi and the poneglyph were the only real points of all this. Was unnecessarily long, but it just is what it is. I feel like most cover stories are like this, there's a bunch of pages of just nothing......and then boom, something that completely changes the game. So I just look at it this way: every cover story has AT LEAST 1 major takeaway that if it doesnt pop up in the main storyline, has major storyline implications.

Buggy's Crew - Buggy being alive, his alliance with Alvida, foreshadowing of Loguetown Arc

Coby-Meppo - Their training in the Navy, foreshadowing of their confrontation with Luffy & Zoro Post Enies Lobby

Jango - Joining the Marines, him and Fullbody at Marineford

Hatchan - meeting Keimi, and they both appear in Saobody, with Hatchan sparking one of the most important moments in the series

Wapols - Dalton becoming king of Drum/Sakura Kingdom, which could certainly play a role at the Reverie. As for Wapol, foreshadowing of him becoming a King again

Ace/Blackbeard - Rockstar/Shanks - Whitebeard meetings, Marineford, 'nuff said

Gedatsu - Nothing so far, but we certainly expect to see Alabasta people again, and helping Kohza's uncle could certainly earn him some respect in Alabasta with the project they're working on, for a place that had been suffering droughts

Miss Goldenweek's Operation - The actions of Baroque Agents 0-3 in Impel Down and Marineford

Enel's Space Operation - The fact that there was, and is life outside the actual One Piece Earth. Rumors off extra-terrestial life are definitely not a new thing, and there is an obvious connection between these old moon races and the Skypeians/Shandia, who we also might most likely see again. There's also the Celestial Dragons, and their space costumes as another potential link.

CP9 - The fact that they are all still alive, and currently on the move. It certainly makes sense that we'd see them again, they have a rather in-depth knowledge of many things World Government related, and now have a vendetta against them. They've shown they don't care to take down Marines, so I think they're gonna cause some major ruckus, and might even help out the SHs.

Separation Serial - Timeskip

From the Decks - Updates on various important people. Luffy will more than likely see people like Makino, Dadan, Woop Slap again, due to their importance to him. We will most likely see people like the Usopp Pirates and Kaya again, due to their importance to him. I could go through this for just about everyone important to the SHs, but here's my main ones from this series: Alabasta people - The Reverie, Wapol - his new Kingdom/The Reverie, Ace/Whitebeard graves -  Sabo being alive, Perona going to Thriller Bark - seeing Moriah again

Caribous - Drake's alliance/affiliation/business with Kaido, confirming Drake can use Buso Haki, seeing Drake in Law's flashback

Jinbei - As discussed, the Poneglyph obviously gets the spotlight. For the simple fact that we're now in the New World, poneglyphs are going to start have much more important messages for Robin to decipher. The message on this is probably going to be absolutely critical to them learning more Void Century history.

All that aside, this most recent one of Luffy trying to force Law to eat bread >>>>>> all the previous.
