So I caught up on the last 4 chapters from

Kaidou fight to Pt.1 end -> Intermission -> Pt.2 start
And that was all pretty darn awesome. This is good stuff.
Ok, so the main thing I'm wondering is at the end of the day this is a shounen manga. For Luffy to become the Pirate King he eventually needs to be stronger than everyone. We saw that as he grew in strength and beat the Shichibukai, but now that he's in the New World he got smacked down by Big Mom and at best only tied against her 2nd in command and

Against Kaidou he couldn't do much damage and got 1-hit KO'd
Now in the shorter amount of time left in the arc/series, I wonder how the hell Luffy is going to power up that dramatically from here. I mean he already has all the various armaments and 4th form was still pretty recent. Another form doesn't feel like it'd give him the power boost he needs to be competitive on the Yonkou scene. Will be interesting what happens in this arc because you've got to assume that he will beat Kaidou in the end and this will be the arc that gets him to Yonkou tier in power-level. If he runs again after Big Mom arc that'd be weird.
Awakening most likely. Also remember he lost to Croc three times in the same arc. It didn't come easy. First time they "fought" he got one shotted and had his blood sucked out. Luffy lost against Lucci once in Water 7 before their rematch at Enies Lobby. Luffy barely survived Impel Down. Luffy got his ass dragged by Mochi boy almost their entire fight and he won in the end. Also, I highly doubt Luffy and co. will get One Piece as is. I fully expect there to be another time skip before they set foot on Raftel. Also, more than likely Luffy doesn't even take on Kaido himself. It'll be a multi-man job. I'm betting Law, Kidd, AND Luffy take him on. Maybe even Hawkings too.
Also, I'm expecting Luffy's fleet to come and save the day.
I don't think the Worst Generation have gotten cameos at all. Oda has slowly built them up over time. We didn't know shit about Bege until Whole Cake. We've learned Law's backstory. Wano has Law, Kidd, Hawkings, Apoo, and likely Killer as well. Including Luffy and Zoro that's over half of the Worst Generation in one location. Guarantee we learn about Kidd this arc. Also, Reverie had Jewelry Bonney. Oda seems to be applying a slow burn to the Worst Generation but they in no way seem to be afterthoughts. The Worst Generation characters we've run into so far such as Bege and Law have both played major roles for instance.
