Why is the Myrmidon still so commonly used for space superiority even in TEI battlegroups? Is there a massive surplus of Myrm hulls as a result of some politicking in the Capella era? Is it supposed to be more noob friendly than the Perseus or Herc 2? With the Myrm's fighter-bomber update perhaphs bomber pilots are using it when pressed into CAP due to other squadrons not being available?
Think Super Hornet. It's filling a requirement for a long-lived and affordable space superiority design. Also it has six gun points.
Does the Vasudan Imperium have any special objectives in the Sol Theater, beyond what we have already been told?
They're more interested in the looming metaphysical/Shivan-related crisis than in the Sol theater, but they are
engaged in that theater to the extent that it bears on said crisis: which, they're realizing, is a lot more than they thought.
Also the Hammer is a factor.
What's going on with captured GTVA ships by UEF? What is the super secret project that 1st Fleet is working on, with ships defected to UEF like Lambouchere and captured tech from logistic ship? Will we see beam-equipped UEF warships?
Will we see Sanctuary again? What is her role in further events?
The captured GTVA ships supplied vital reactor and power system knowhow to Project Shambhala, but perhaps their most important contributions were the records they gathered during their journey into the Sanctuaryverse. I don't think we have firm plans for/against UEF beams in very special cases (like a special bomber weapon, maybe) but they aren't going to be a huge strategic turning point.
The Sanctuary is full of people who've spent years hibernating under Vishnan influence. They'll definitely be important.
Will we ever meet Brie or Kassim again?
And I assume that the next time Laporte contacts with Ken is going to be rather face-to-face? (Ending of UT2, "We can't speak ever again" or something suggesting that Laporte or Ken is being watched by someone from now on)
No firm outline pinning exactly when Brie or Kassim will show up, but I think Brie at least will pop up again as a yardstick for Laporte's growth. And yes, Laporte's role as a deniable asset requires that Ken go pretty hands-off.
