Danmachi 'Shippuden'

With the author confirming that we are in the final saga (likely ais and oebd arc) , it's now obvious that we won't have time for all the plot around the dungeon and the xenos , so my question is how high are the chance of a new series kinda like 'naruto shippuden' where the character are older after a timeskip and we see them diving the dungeon for the 'promised time'
