I'm also getting very interested in the magazine part of the subscription.
For the Ent-D and Constitution class and others, there's plenty of material to fill an issue.
When we get to the Akira class and Breen warship and Steamrunner... what we will get? There's almost no official or canon material on those ships besides the visuals.
What data and info will be in the magazine? What sources? What conjecture? Who will be writing about the Xindi ships, for example?
