The way the story is moving right now we are already able to chain alot of the events that will follow together: heads to Wano, Reverie, Kaido, Big Mom, Shanks and finally a showdown with Blackbeard at Raftel or something. Then of course there is the whole Revolutionary/WorldGovernment affair going on that will of course also happen with some input from the Strawhats.
Gold D. Roger’s generation were all adults (Rayleigh, Whitebeard, Shiki, Monkey D. Garp, Sengoku, Crocus). Luffy and his crew members are almost all 20ish. People of his generation are also fairly young, Coby said it’s his dream to become an Admiral and the Supernovas are in Luffy’s generation. Furthermore Luffy isn’t strong enough to take on a Yonko 1v1.
What I’m asking is: Is there some point in the following arcs where we could see another Timeskip happening? Is it really necessary for growth? What do you think?
