Recently, the leaker YonkouProd provided fans with a major indication by stating that Blackbeard will play a significant part in this next chapter.
Not only Blackbeard but Boa Hancock would also play an important role in this upcoming chapter as well

A crying Perona was shown reading a newspaper in the first clue, which was obviously about Gecko Moria.
Fans speculated that because Moria was last seen with Blackbeard, the Yonko would either appear or be referenced in the news.
The fact that Boa was also visible in the picture, though, led some fans to speculate that Blackbeard and Boa would show up together in the chapter for some reason.
Recently, nothing has been certain, therefore it is better to be ready for everything, even Gecko Moira's return to the plot.
