Maybe at the last minute before season 7 hits, it'll be announced to include a romulan faction? I know this has been discussed a lot, but for once I actually wonder if it might happen.
They dont even have time to bring the KDF up to date. And they have a number of issues game-wide regardless of faction to deal with. Why are you getting your hopes up for something you know for certian is just not going to happen in the forseeable future?
