i don't think the tashigi issue will be resolved at all, NOR DO I THINK THE LABOON ONE WILL. I think that a lot of the next arc will focus on resolving all those issues because think about it in 388 the old lady even said that he would become known throughout the world. This could lead to:
Shanks locating him and doing something, Buggy and Alvida locating him, Him becoming a candidate for the next pirate god(if it hasn't already been dicided which it may have been), blackbeard appearing again, his actions distracting the navy from what shanks and whitebeard are doing, or any of many other things. Also there is another unresolved issue that noone ever mentioned: Who are the other two Supremem admirals of the navy(the position that Ao Kiji holds) and what are they going to do if luffy becomes extremely powerful?
