I'd expect everything to stay rather generic (I'm sort of surprised that things like "Goliath Scorpion Seeker" remained in, instead of say, a generic "Explorer" module with a Seeker part). Part of the problem that MW3rd had was the power creep of Life Paths, along with just how many of them there were.
If they were to do Affiliation Specific stages, then they'd have to start doing Affiliation specific stages for everyone. Davion gets a NAIS? Lyrans get a Nagelring. MoC a Canopus Institute of War.
The way its done now allows for it to be flexible enough to cover everyone, without becoming to unwieldy, or having a hundred pages of modules that are superficially similar.
