It occurred to me that the PDFs themselves seem to be somewhat divided into two major groups, in terms of their respective orders of publication; ones which echo the major theatres of conflict in the Inner Sphere as of 3145.
With the Liao(-Centrella) and Kurita files set to be followed by the Davions, the three most active protagnists/antagonists (depending on one's point of view) are all listed one after another in the release schedule. And once they are done, the focus will shift to anti-spinward; with the Marik, Steiner, and Clan (to include that other Steiner) files rolling out before the spotlight doubles back towards the Republic of the Sphere itself.
It will be interesting, once the Federated Suns get their file out, to see the discussions started in Bonfire (and which seem to have been somewhat eclipsed by talk about the spinward side of the Sphere ever since ER:3145 went up) emerge a little more prominently, perhaps.
