I dont know how credible the One Piece Wiki is in terms of information provided there so this post may not be as accurate as I want because I am basing it on info from the Wiki. As per the wiki there are 11 sagas in total until now and the post Wano period is listed as the Final Saga. When you compare the length of each saga you see that there are some very small ones like 40-50 chapters long and then you have the biggest Wano at 149 and DR at 148 chapters long.
The problem though in the post Wano period being called the Final Saga is that we are already 94 chapters into the saga and we have got Egghead and Elbaf (continuing). Based on the history of OP we are only 56 chapters away from this being the longest saga. Of course there is no official limit to how many chapters a saga can have or if the Final Saga is actually the final saga (its just used as a name and we get a new saga to wrap things up). But lets pretend that this is actually the Final Saga and lets increase the chapter limit from 149 to 200, even then it translates to like 3 years of serialization at max with about a 100 chapters to go.
The really scary part is not that OP ending is so close, it is that the fandom expects a clear and adequate ending and based on the plot points remaining its hard to believe that Oda will be able to address them as expected in 100 chapters.
We barely know anything about the current expected villains (Imu and Gorosei and HKs), where will we get the BBPs being built up as the villains, and as the final villains you expect them to get developed more than any previous villains. There is too much anticipation and hope for the mysteries to get solved and then you realize that there may not be enough time. And I hope Oda doesnt waste time on side characters now, we had too much of them in DR and Wano.
Then again, maybe this was the plan all along and the prepare for a roller coaster type comments were actually meant and not just empty hype.
