Well Matthew has now confirmed to me that I can talk about what ACTA stuff I saw, but points out that all the details will likely change.
I saw fleet lists for the ISA, Pak'mara (Tenacious will love that after how I quietened hium down about the Dilgar), Gaim and PSI CORPS.
The ISA get all new ships from existing canon, the Psi Corps stuff looks well cool, the Pak had a rather nice fighter (subject to change) and I never really touched the Gaim list.
Also there was an 'Other ships list' which included lots of varied civilian shipping from many races, abnd something Derina will like, a Technomage pinnace.
But like I say, all subject to change.
