Player housing has not been announced yet. It’s just a rumor so far. But looking at the “Welcome Home” message along with seeing the mailbox and repair droid, it definitely looks like it could be player housing.
Coruscant makes sense for the Republic. I am curious where the Imperials would set up shop. Dromund Kaas is the equivalent planet but it’s not as exciting of a location. I’m actually hoping that there’d be multiple locations available. A hideout for my Smuggler on Nar Shaddaa would be great. Even though Corellia is war-torn, it’s still a beautiful place.
