I have to say that after looking at the GM section, I was extremely surprised to see that you intend to be progressing the timeline with new metaplot in each book, a la the Old World of Darkness.
I'd like to request that this not be done, if such an alteration to the plan is possible. While I'm all a fan of secrets of the setting, a rich backstory, and adventure seeds left and right, progressing time is going to damage the campaignability of the setting for the same reason as it damaged the old World of Darkness and Planescape, and continues to damage Rifts.
1. Obviously, the metaplot circa 30 A.F. will be rather different from the status quo of a campaign that started in 10 A.F. and progressed twenty years. If you had a plan to reveal the Jovian Junta's plan to annihilate transhumanity with their new superweapon, which will wipe out half the setting and make nothing be the same anymore, but in 22 AF the PCs of that early campaign overthrew the Junta and established the Jovian Autonomous Commonwealth, no setting books after 30 AF will be of use, because they detail a Locus made of gray goo and not a Locus at the center of the new Renaissance.
2. A lack of an "absolute now" means that as the setting changes, and the rules change, Mars' toys and developments may be at 18 A.F. while Venus is at 25 and the Jovian Junta is at 30 A.F. post-superweapon. And, of course, all of this interconnected disjunction can be set off by the campaign events, requiring GM patching just to be able to use new sourcebooks.
Sorry if I got too high on my soapbox there. I just think that this is one of those parts of gaming tradition that makes games harder and harder to use and locks out new players. Having all your sourcebooks set in and detailing the world of 10 A.F., with the plans and attitude of every organization and all the various threats to transhumanity that might pop out of the shadows in the near future (for Firewall to hit with a whack-a-mole bopper) would make the game better, and I'd be thrilled to see this happen instead of an advancing metaplot.
