Yeah, perhaps. I mean the Carasuma thing is a huge development (though it's just a name), but that very possibility been discussed on DCTP as well. It puts a new light on certain things (for example Gin's words that Rum screwed something back then probably mean that Rum left the name of the BO on a crime place (but then again that 15 years proved that it was not a big deal anyway)), but that's all. Like You already state to someone else, we still need to reveal who's Rum, Mary must still learn how to trust people, Haneda must still learn how to play chess, Asaka must still learn how to be a normal woman, Conan must still take down Gin, Vodka, several other people, become friends with Vermouth and finally confess to Ran, and above everything else Gosho must stop giving us scraps of meat and start focusing on finishing the story. He was unable doing so through over 20 years, so I doubt he will start doing that now. Plus, he has now some health issues which as well could change into several months of break. Thankfully Gosho plays only Animal Crossing, and not - for example - Dragon Quest. In other words finishing all what he started requires still a lot of time and chapters, so I doubt that with the current flow of plot he will be able to finish them in a reasonable amount of time/chapters.
