To clarify with what I remember of devcomments lately: originally the book was supposed to bring 3150 and the 'dark age' era to close, and institute at 100 year timeskip to bring us to 3250 With the new line dev and others, they've decided not to do the timeskip, and instead focus on the post-3150 era with the extant apparent-ilClan being part of the new round of the game.
I'm not a big fan of timeskips, I admit, especially BIG ones like that hundred year jump. Look how much happened in the 100 years from 3050 to 3149, to suddenly 'status quo nothing happens' for an equal amount of time feels very oddly wrong. It also gives a big chopping off of all of the characters that we've started to enjoy by handwaving whatever might have been for their future, and not giving them a chance to be more than a footnote.
