So, the Starkiller Base loading screen is broken in-game. The one from Strike is used in Galactic Assault and most other game modes and has unfortunately been this way for a while. It talks about sabotaging TIEs instead of liberating prisoners as it should. Command Center is a smaller map that uses a section of Precinct 47, as the latter name comes from the website and in-game before the bug. I believe, it's the only smaller map, within a map, that has a separate name.
I see. Thank you the source. Ben doesn't outright say more villain appearances will be coming in 2020, rather, that they will be prioritized over "old version" appearances. So for what you wrote I would change the wording to be less definitive, even though for all intents and purposes some will end up being released in 2020. Does that make sense?
