I skipped to the universe background section, and I noted that while part of it has been updated to account for the current shift to the Dark Age, other sections still read as if the Jihad was still the "present" era.
For example, the history section goes as far as the post-blackout Dark Age, but the faction writeups seem to assume one is still in the Jihad. (For example, the Free Worlds League section does not refer to the dissolution in 3079, or the partial reformation in 3139. While the House Steiner section refers to the Lyran Alliance, not the Commonwealth as it reverted to in 3084.)
Also, on page 157, the Plot Sourcebooks section notes that the Dark Age is the curent era, but the Historical Sourcebooks section in the next paragraph refers instead to "the current Jihad".
Plus, the map seems to be set in 3067, but doesn't specify what year it's supposed to cover. (I would have hoped for either a map set in the Clan Invasion era, to support the initial setting, or a 3145 map to show the state of play as we await the ilClan sourcebook.)
It's probably too late to do anything about this for the first print run, but it might be something worth re-considering for errata purposes.
