Something tells me the main story has more or less come to a close. I don't know for sure.
What I sincerely hope is that Bioware gives us some sort of class-specific companion reunion chapter. Jedi Knight reunites with Kira, Doc, and Scourge; Trooper reunites with Elara and Tano Vik (if you didn't kill him); Bounty Hunter reunites with Mako, Consular reunites with Tharan, Zenith, Iresso, and Nadia, etc. At this point in the story, there's no reason they wouldn't be able to find you. Especially for the romanced companions. I resisted the urge to flirt with Lana with my knight under the assumption that I would have some sort of romantic reunion with Kira.
I'm still really hoping for that. Question is, will they pay all those voice actors and actresses to do a few lines of dialogue just for that wish fulfillment? We'll see.
